Answer 2

Dear Student,

◆ Answer - (2)

Frequency of sound = 500 Hz

◆ Explaination -

Given that tuning fork vibrates 10,000 times per 20 seconds.

Frequency of sound generated is -

Frequency of sound = no of vibrations / time

Frequency of sound = 10000 / 20

Frequency of sound = 500 Hz

Hence, the sound generated by thefork will have a frequency of 500 Hz.

Thanks dear. Hope this helps you...
