Question

a) What are the characteristics of sound? Define them.

b) How does the pitch of a sound depend on the frequency?
​

Answer 1

Answer:

The sensation of a frequency is commonly referred to as the pitch of a sound. A high pitch sound corresponds to a high frequency sound wave and a low pitch sound corresponds to a low frequency sound wave.

Answer 2

Answer:

A sound is a form of energy that propagates in the form of longitudinal waves.

Explanation:

Sound waves are longitudinal waves. They require a medium for their propagation. 5 important characteristics of sound waves are amplitude, wavelength, time period, velocity, and frequency.

The amplitude of the longitudinal wave determines the loudness of the sound wave. The wavelength is the maximum displacement of the particle from its mean position. The time period is the time required to execute one complete cycle of vibration by the particle of the medium. The velocity of the sound waves defines how fast the wave is being propagated. At last, the frequency of the sound wave defines the pitch of the sound.

If the frequency is higher then the pitch will also be higher and vice versa.
