If 25 sound waves are produced per second, what is the frequency in hertz?

Five beats per second are produced on vibrating two closed organ pipes simultaneously. If the ratio of their lengths is 21 : 20 , then their frequencies will be

If 20 waves are produced per second, what is the frequency in hertz?

Two sound waves produce 12 beats in 4 second. By how much do their frequencies differ ?

Two tuning forks A and B are sounded together and it results in beats with frequency of 4 beats per second . When A is loaded with wax, they again produces 4 beats per second . If frequency of A is 256 Hz, then the frequency of B is

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 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 ?
