Question

The frequency of a source of sound is 200 Hz. How many times does it vibrate in a minute?
(A) 200 times
(B)[ tex]\frac{1}{200}[/tex] times
(C) 12000 times
(D) 1200 times

Answer 1

the answer is C .. as N= f*T(sec)

OPTION:-(C)

Frequency is defined as the number of oscillations per second. It is given by the relation:

Frequency = Number of Oscillations / Total Time

Number of oscillations = Frequency × Total time

Given, Frequency of sound = 200 Hz

Total time = 1 min = 60 s

Number of oscillations/Vibrations = 200 × 60 = 12000

Hence, the source vibrates 12000 times in a minute, producing a frequency of 00 Hz.
