Dr. S K Jain and Dr. Shailesh K Jain Solutions for Chapter: Sound, Exercise 6: EXAM PRACTICE QUESTIONS

Describe the inner parts of the human ear.

What do you mean by the loudness of sound?

What do you mean by the pitch of sound?

What is meant by the quality of sound?

What is the frequency of a wave with a time period of $0.05 \mathrm{s}$?

A body vibrates with a time period of $2\times {10}^{-3} \mathrm{second}$ to produce a wave having a velocity of $1250 \mathrm{m}/\mathrm{s}$. Calculate its wavelength. 

The density-time graph at a particular point in the medium when a sound wave passes through that point, is shown below:

Find the time period and frequency of the wave.

The density-time graph at a particular point in the medium when a sound wave passes through that point, is shown below:

 If the velocity of wave is $340 \mathrm{m}/\mathrm{s}$, find its wavelength.
