Question 6: Waves

Question

Assertion To hear different beats difference
of the frequencies of two sources should be
less than 10.
Reason More the number of beats more in
the confusion.

Accepted Answer

According to the property of persistence of hearing the impression of a sound heard perist on our mind for $$\frac{1}{10} \mathrm{~s}$$. To hear distinct beats, time interval between two successive beats should be greater than $$\frac{1}{10} \mathrm{~s}$$. Hence, difference in two frequencies must be less than 10.
