Two stationary sources A and B produces sounds of same frequency. A person running from A to B hears 5 beat/s.If the frequency of each source increases by 100Hz ,now the 8 beats/s are heard. Then the original frequency of each source is

Two tuning forks A and B give 6 beats/s. The frequency of B is 432 Hz. When B is filed 4 beats/s are produced. The natural frequency of fork A is

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

A sound source of frequency 512 Hz is producing 6 beats with a guitar. If the string of gultar is stretched slightly then beat frequency decreases. The original frequency of guitar is

In a guitar , two strings A and b made of same material are slightly out of tune and produce beats of frequency 6 Hz. when tension in B is slightly decreased, the beat frequency increases to 7 Hz. If the frequency of A is 530 hz, the original frequency of B will be

Two strings X and Y of a sitar produce a beat frequency 4 Hz.When the tension of the string Y is slightly increased the beat frequency is found to be 2 Hz. If the frequency of X is 300 Hz,then the original frequency of Y was

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 sources of sound produce 20 beats in 4 second. What is the difference in frequencies of the two sources?

Two tuning forks A and B of frequency 512 Hz are sounded together produce 5 beats/s. If the fork A is thin loaded with a piece of wax and found that beats occur at shorter intervals. Then the natural frequency of A will be
