Two vibrating tuning forks produce progressive waves given by y 1 = 4 sin 500 π π t and y 2 = 2 sin 506 π π t. Number of beats produced per minute is:-
Text Solution
Verified by ExpertsThe correct answer is:
B
To reach the solution the given wave equations must be compared
with standard equation of progressive wave.
So, 
(i)
(ii)
Comparing Eqs. (i) and (ii) with
(iii)
We have,
beats 
and 
beats 
Thus, number of beats produced
beats 
beats 
beats
