List of top Physics Questions on sound asked in KEAM

When a tuning fork of frequency 256 Hz is sounded together with unknown tuning fork, 4 beats are heard in one second. The frequency of the unknown tuning fork can be

A source of frequency \(f\) gives 5 beats/sec when sounded with a source of frequency 200 Hz. The second harmonic of \(f\) gives 10 beats/sec when sounded with a source of frequency 420 Hz. The value of \(f\) is:

Consider the propagation of sound (with velocity $330$ m/s) in a pipe of length $1.5$ m with one end closed and the other open. The frequency associated with the fundamental mode is

A standing wave propagating with velocity $300$ m/s in an open pipe of length $4$ m has four nodes. The frequency of the wave is
