Question

Q. 4. Answer the following questions :
(1) How is sound produced?
Ans.
(2) What does the intensity of sound depend upon?
Ans. ....​

Answer 1

1. Sound is produced when an object vibrates, creating a pressure wave. ... As the particles vibrate, they move nearby particles, transmitting the sound further through the medium. The human ear detects sound waves when vibrating air particles vibrate small parts within the ear.
2. Intensity results from two factors: the amplitude of the sound waves and how far they have traveled from the source of the sound. ... It depends on the amount of energy that started the waves. Greater amplitude waves have more energy and greater intensity, so they sound louder.

hope it's help u..!!
