“DAIJA” It was Monday morning when the phone rang. It was my mother. After talking for a minute, she said “I am giving the phone to someone. Talk to her." "Hello," came a familiar voice and I immediately knew who was at the other end. I was very happy to hear that voice. It had been too long. "Daija! How are you? When did you come there?" "Just yesterday. I am fine. How are you?" said Daija Daija was my grandparents' helping hand for many years. She came to work for them almost 51 years ago. My mother was just seven years old then. Daija came unannounced. She had heard that my grandparents were looking for a maid and she travelled for two days to apply for the job. She was around 20 years old then. Daija was puny. She frequently laughed out loud. Her husband had left her for another woman but this had not embittered her about life. Slowly, she became part of the family. Her real name was Kamlaben but my mother would call her “Daija" affectionately and it stuck to her for the rest of her life. Her personality was such that she became the life of every festival and get-together. She was a good dancer and though she did not have a good voice she enjoyed singing too. When my mother was married and moved to another town, Daija cried more than my grandmother. When my mother was pregnant she came to live with her. Every winter, we used to go to our grandparents’ place for holidays and she became our playmate. She would hide some special food from my grandmother to give us later. My grandmother could not do without her. When my grandfather died 10 years ago, she became my grandmother's sole companion. They had disagreements but that didn't bother either of them. But once grandfather was gone, Daija started feeling insecure. My grandmother, who was six years older than Daija, was also not keeping well. Daija would take care of her but who would take care of Daija? She was already 72. One day, she came to my mother and took out about Rs. 6,000, which she had saved. She said "Kamala, please secure a place for me in an old age home. I may not be staying here for a long time." My mother dismissed her but that act remained in her mind. Sometimes, she would discuss Daija’s future with my father. Daija, too old by now to do everything herself, had other maids helping her. She was now the task manager. At times, we could not differentiate her from our grandmother. She was as influential. Then, one day after 45 years, without warning, her husband came to visit her. She had no feelings. She had not seen him for all these years. The other woman had passed away leaving her grown-up son, who was earning decent lives for themselves. The husband himself had made a name in palmistry. Now he was expecting her to come back. She was not sure. He left without an answer. It took her a long time to decide. She finally decided to go .The day she left, a vacuum was created in our lives. There was no one to take her place. Today, we miss her laughs, her unconditional love and her spontaneity. She still visits my grandmother on every festival. These days, Daija has been travelling around with her husband, and his son takes care of her. Some people like Daija leave a void in lives, and are always remembered.

Q Find words from the passage which mean the same as the words given below: 1 x 3 = 3 marks a) space b) avoided c) readiness Q Read the following passage carefully: 5 marks Have you heard people saying that the 'rupiah makes the world go round? Do you know the story of the rupee? The word rupee comes from the Sanskrit term ‘ Rupya’ or ‘ Rupa’ which means silver. The very early coins before the second century BC, were all made of silver but the coins were neither of any standard weight nor had any face or value printed on them. It was Sher Shah Suri who first gave the name “rupia” to the silver coins. The last silver coins were minted in 1940 with the face of King George VI on them. In 1942 the silver coin was replaced by a cupro-nickel coin for the first time. Money was invented by man to get power but now money has become more powerful than man. All over the world, money and power go together. The more money a person has, the more successful he is judged to be. A rich man is accepted by society even if he is corrupt or evil. Man works hard to earn more and more money and saves a lot of it. He thinks that money will give him more freedom to enjoy himself and to have lots of fun. He thinks he will not be anyone's slave but be his own master. But soon he becomes the slave of money. The more he has, the more he wants. He is never satisfied with what he has got but always wants something more even though he knows that in the end, he cannot carry anything with him. Money can buy everything but it cannot buy peace or happiness or a ticket to heaven.

Discovery of Electron Who discovered the electron? Electron was discovered by J. J. Thomson in 1897 when he was studying the properties of cathode ray. What is cathode ray? J. J. Thomson constructed a glass tube which was partially evacuated i.e. much of the air was pumped out of the tube. Then he applied a high electrical voltage between two electrodes at either end of the tube. He detected that a stream of particle (ray) was coming out from the negatively charged electrode (cathode) to positively charged electrode (anode). This ray is called cathode ray and the whole construction is called cathode ray tube. The schematic of a cathode ray tube Conclusion s: o Cathode rays consist of electrons. o Electrons are the basic unit s of all atoms. Properties of cathode ray particle 1. They travel in straight lines. 2. They are independent of the material composition of the cathode. 3. Applying electric field in the path of cathode ray deflects the ray towards positively charged plate. Hence cathode ray consists of negatively charged particles. J. J. Thomson measured the charge-by-mass-ratio (e/m) of cathode ray particle using deflection in both electric and magnetic field. e/m =−1.76×108 coulomb per gram The cathode ray particle turned out to be 2000 times lighter than hydrogen. Although we got e/m ratio for electron from J.J. Thomson’s Cathode Ray Tube experiment, we still don’t know the exact charge (e) for electron. American physicist Robert Millikan designed an experiment to measure the absolute value of the charge of electron which is discussed below. Millikan Oil Drop Experiment In 1909, American physicist R. Millikan measured the charge of an electron using negatively charged oil droplets. The measured charge (e) of an electron is −1.60×10−19 Coulombs. Using the measured charge of electron, we can calculate the mass of electron from e/m ratio given by J. J. Thomson’s cathode ray experiment. e/m=−1.76×108 Coulomb-per-gram m=e−1.76×108 Putting e=−1.60×10−19 Coulomb, m=9.1×10−28 gram. What we have learned Electron was discovered by J. J. Thomson in Cathode Ray Tube (CRT) experiment. Electrons are negatively charged particles with charge-to-mass ratio −1.76×108 C/gm The charge of an electron was measured by R. Millikan in Oil drop experiment. Charge of an electron is −1.60×10−19 C Mass of an electron is 9.1×10−28 gram. Electron is approximately 2000 times lighter than hydrogen. Discovery of Proton
Q.What is refraction of light? What are the laws of refraction? Ans: Deviation of ray of light from its original path when it travels from one transparent homogeneous medium to another transparent homogenous medium is called the refraction of light. There are two laws of refraction :- (I ) incident ray, reflected ray and normal lie in the same plane. (ii) The ratio of sine of angle of incidence and sine of angle of refraction is constant i.e. Sin i / Sin r = n. This is also called as Snell’s law. Q. Define Refractive Index: Ans: It is the ratio of speed of light in vacuum to the speed of light in medium is called Refractive index. Q. Give the ratio of velocities of two light waves travelling is vacuum and having wave lengths 4000A0 and 8000A0. Ans: In Vacuum, light of all the wave lengths travel with the same velocity i.e. 3 X 108 m/sec. Q.. For what angle of incidence, the lateral shift produced by parallel sided glass plate is zero? Ans: For <i = 0. Q. What are the factors on which the lateral shift depends? Ans: Thickness of the refracting medium, angle of incidence and its refractive index Q. What is the value of Relative refractive index of air? Ans: One. Q. If speed of light in vacuum = 3 x 108 m/sec and Refractive index of water = 4/3, What is the speed of light in water? Ans: Refractive index of water = Speed of light in vacuum / Speed of light in water; 4/3 = (3 x 108 m/sec )/ (Speed of light in water) Speed of light in water = (3 x 108 m/sec) x ¾ = 9/4 x 108m/sec = 2.25 x 108 m/sec. Q. For the same angle of incidence in media P, Q and R, the angles of refraction are 350, 250, 150 respectively. In which medium will the velocity of light be minimum? Ans: According Snell’s law n = Sin i / Sin = C / V For given angle of incidence (i), V will be minimum, when angle of refraction <r is minimum In given data it is for medium R. Q. A coin in a glass beaker appears to rise as the beaker is slowly filled with water. Why? Ans: It happens on account of refraction of light. A ray of light starting from the coin goes from water to air and bends away from normal. Therefore, bottom of the beaker on which the coin lies appears to be raised.
