Question

Explain the difference between beats and interfrence.

✓

Answer

S.No.	Beats	Interference
1	In this both the sound wave have almost the same frequencies.	In this, the frequencies of both sound waves are same.
2	At every point of medium amplitude value of time keeps changing with.	at every point of the medium value of amplitude remain constant.
3	The phase diference between waves at any point in the medium changes with time.	at each point of medium phase difference is constant
4	In beats the value of sound intensity at each point becomes heighest and lowest in alternating order with time in lives	interference the value of sound intensity at a particular point remain constant
