This is the most confusing question related to class 8 science chapter sound Q.will sound wave having frequency of 144Hz and 240Hz produce a musical sound?Why? Jsunil sir blog Visit , comment and subscribe www.Jsuniltutorial.in Correct answer is: Yes , sound wave having frequency of 144Hz and 240Hz produce a musical sound because musical notes is produced by a combination of frequencies which are in a simple ratio of whole number with each other . Class 09 Chapter sound Examples : Sound of frequencies of 261.62Hz,523.24hz and 784.86Hz produced one after another produce a musical sound as they are in ratio 1:2:3 Question related to Eureka plus science book In Indian classical music, the seven main musical notes are known as "Saptak Swaras." Each of these notes is associated with a specific frequency, and they form the basis of melodies and ragas. The frequencies can vary slightly depending on the tuning system and reference pitch used, but I'll provide you with approximate frequencies for these notes: 1. Sa (Shadja) - The tonic note: Approximate Frequency: Around 220Hz (in the middle octave) 2. Re (Rishabh) - The second note: Approximate Frequency: Around 246.94Hz 3. Ga (Gandhar) - The third note: Approximate Frequency: Around 293.66Hz 4. Ma (Madhyam) - The fourth note: Approximate Frequency: Around 329.63Hz 5. Pa (Pancham) - The fifth note: Approximate Frequency: Around 392.00Hz 6. Dha (Dhaivat) - The sixth note: Approximate Frequency: Around 440.00Hz 7. Ni (Nishad) - The seventh note: Approximate Frequency: Around 493.88Hz These frequencies are based on the equal temperament tuning system and are given for the reference pitch of A4 being 440Hz. Keep in mind that in different styles of Indian classical music and different tunings, these frequencies might vary slightly. These notes and their frequencies form the foundation of Indian classical music, and melodies are created by combining these notes in various patterns and sequences. Conclusion
Yes, the sounds of frequencies 144Hz and 240Hz can indeed produce musical sounds. In fact, these frequencies fall within the audible range of human hearing, which typically ranges from about 20Hz to 20,000Hz. In the context of music, these frequencies would correspond to specific musical notes. The pitch of a sound is determined by its frequency, where higher frequencies correspond to higher pitches and lower frequencies correspond to lower pitches. For example, the note A below middle C on a piano is typically tuned to a frequency of 440Hz. If you were to play a note with a frequency of 144Hz, it would be a lower pitch than the A below middle C, while a note with a frequency of 240Hz would be a bit higher in pitch. So, when you play sounds with frequencies of 144Hz and 240Hz, they will produce musical tones that can be perceived by our ears and contribute to the overall musical experience. These frequencies, along with many others within the audible range, are used in various combinations to create melodies, harmonies, and rhythms in music.
