Waves Test - 13...

Two guitar strings A and B are slightly out of tune and produce beats of frequency 6Hz.The tension of the string found to decrease to 4 Hz. What is the original frequency of B if the frequency of a is 430Hz?

When two tuning forks are sounded together 4 beats are heard per second. One tuning fork is of frequency 346 Hz. When its prong is loaded with a little wax, the number of beats is increased to 6 per second. The frequency of the other fork is:

What material is tuning fork made of and why?

Phenomenon of beats is not used in

For the formation of distinct beats, the frequencies of two sources of sound should be

On adding two sine waves that are exactly the same, what would be the result?

Time interval between two successive maxima of sound waves with frequencies v₁ and v₂ is given by

Two sound sources fixed at a given distance apart are emitting sound each of wavelength λ. A Listener moves with a velocity v₀ along the line joining the two sources , the number of beats heard by him per second is

Pure sound notes from two sources make the molecules of air at a location vibrate simple harmonically in accordance with the equations.
y₁ = 0.008 sin (604 n t) and
y₂ = 0.007 sin (610 n t) respectively.
The number of beast heard by a person at the location will be:

Two tuning forks are struck and the sounds from each reach your ears at the same time. One sound has a frequency of 256 Hz, and the second sound has a frequency of 258 Hz. The underlying beat frequency is:
