Question

what is the frequency of the source of sound if the vibrating source of sound makes 360 oscillations in 2 minutes

Answer 1

ANSWER
.........

=360 cycles per 2 min
= 360 cycles/120 sec
=2 cps= 2 Hz

$= = = = = = = = = \\ < > < > < > <$

Answer 2

Frequency = Total number of oscillations in 1 second
2 minutes = 2 x 60 = 120 seconds

In 120 seconds 360 oscillations
In 1 second ,
Number of oscillations = 360/120 = 3

Hence, the frequency = 3Hz
