$A$ tuning fork produces waves in a medium. If the temperature of the medium changes,then which of the following will change?

Two tuning forks have frequencies $380 \, Hz$ and $384 \, Hz$ respectively. When they are sounded together,they produce $4 \, beats$ per second. After hearing the maximum sound,how long will it take to hear the minimum sound?

In the production of beats by two waves of same amplitude and nearly same frequency,the maximum intensity is how many times the intensity of each of the constituent waves?

The maximum number of beats per second that a human ear can distinguish is

Two identical wires have the same fundamental frequency of $400 \text{ Hz}$ when kept under the same tension. If the tension in one wire is increased by $2\%$,the number of beats produced will be

When two sound waves are superimposed,beats are produced when they have
