The number of beats heard per second if there are three sources of frequencies `(n-1)`, n and `(n+1)` of equal intensities sounded together is :

The maximum number of beats that can be heard per second is

A sources of sound gives 5 beats per second when sounded with another sources of frequency 100 second^(–1) . The second harmonic of the source, together with a source of frequency 205 second^(–1) gives 5 beats per second. What is the frequency of the source ?

A certain number of beats are heard when two tuning forks of natural frequencies n_1 and n_2 are sounded together. The number of beats heard when one of the fork is loaded

A source of sound gives five beats per second when sounded with another source of frequency 100s^-1 . The second harmonic of the source together with a source of frequency 205s^-1 gives five beats per second. What is the ferquency of the source?

A source of sound gives 5 beats when sounded with another source of frequency 100 Hz. The second harmonic of the source together with a source of frequency 200 Hz gives 10 beats s^(-1) . What is the frequency of the source?

Two tones of frequencies n_(1) "and" n_(2) are sounded together. The beats can be heard distinctly when
