Question
Two vibrating tuning forks produce progressive waves given by
. Number of beats produced per minute is
- 360
- 180
- 3
- 60
The correct answer is: 180
Given,


Comparing Eqs. (i) and (ii)
Y=a sin ωt……………(iii)
We have,


And


Thus, number of beats produced

=3 beats/s
=3×60 beats/min
=180 beats/min
