Embibe Experts Solutions for Chapter: Sound Waves, Exercise 5: Exercise (Conceptual Questions)

If at some point the amplitude of the sound becomes double and the frequency becomes one fourth then at that point the intensity of the sound will be:-

Intensity level of a sound of intensity $I$ is $30 \mathrm{dB}$. The ratio $\frac{I}{I_0}$is (where, $I_0$ is the threshold of hearing)

Two vibrating tuning forks produce progressive waves given by $y_1=4\sin 500\pi t$ and $y_2=2\sin 506\pi t.$ Number of beats produced per minute is:

An empty vessel is partially filled with water, then the frequency of vibration of air column in the vessel

What is the minimum length of a tube open at both ends that resonates with tuning fork of frequency $350$ $\mathrm{Hz}$? [velocity of sound in air $=$ $350$ $ \mathrm{m}$ $ \mathrm{s}^{-1}]$

An open resonating tube has fundamental frequency of $n$. When half of its length is dipped into water, then its fundamental frequency will be,

A pipe is closed from one end and open from another end then which statement is true?

A vehicle with a horn of frequency $n$ is moving with a velocity of $30 \mathrm{m} {\mathrm{s}}^{-1}$ in a direction perpendicular to the straight line joining the observer and the vehicle. The observer perceives the sound to have a frequency $n+n_1$. Then (take velocity of sound in air $330 \mathrm{m} {\mathrm{s}}^{-1}$),
