Question

two tuning forks A and B produce 4 beats/sec On loading B
with wax, 6 beats/sec are heard If quantity of wax is reduced, the
number of beats per second again becomes 4 Find the frequency of B
if the frequency of B if the frequency of A is 256 hz?

Somnath physics · Accepted Answer

Let the unknown frequency of the
tuning fork be 'x' So, according to the given data when not waxed,
its frequency must be,
x = 256 +/- 4 to produce a beat
of 4/sec
We know, the frequency of a
tuning fork decreases as it is waxed So, to produce 6 beats/sec,
after being waxed, the frequency of the tuning fork must be x = 256
- 4 = 252 Hz

two tuning forks A and B produce 4 beats/sec.On loading B with wax, 6 beats/sec are heard.If quantity of wax is reduced, the number of beats per second again becomes 4.Find the frequency of B if the frequency of B if the frequency of A is 256 hz?
