Mansi Garg and Jitendra Kumar Solutions for Chapter: Sound, Exercise 3: CHAPTER EXERCISE

Arrange the three medium, according to the speed of velocity in each air, water, solid.

Note: This question given in the book seems to have errors and the modified question should be as given below.

Arrange the three medium, according to the speed of sound in each air, water, solid.

Name the separation between two consecutive rarefaction in a pressure wave.

What name is given to the sound waves of frequency too low for human beings to hear?

A radio transmission produces a frequency of $300 \mathrm{kHz}$. Find its wavelength. The speed of light in air, $c = 3.0\times {10}^8 m/s.$

A sound wave travels at a speed of ${\text{330 m s}}^{\text{-1}}$. If its wavelength is $1.5 \mathrm{cm}$. Calculate the frequency of the sound wave.

Determine the wavelength of an ultrasonic wave of frequency $4.2 \mathrm{MHz}$. The speed of the ultrasonic wave is $1.7 {\mathrm{kms}}^{-1}$.

Establish the relationship between speed of sound, its wavelength and frequency. If the velocity of sound in air is ${\text{340 ms}}^{\text{-1}}$. Calculate the wavelength when the frequency is $256 \mathrm{Hz}$.

Establish the relationship between speed of sound, its wavelength and frequency. If the velocity of sound in air is $340 {\mathrm{ms}}^{-1}$. Calculate, the frequency when the wavelength is $0.85 \mathrm{m}$.
