Question

When are beats generated in two interfering waves?

Answer 1

Beats are generated by two interfering waves when they have slightly different frequencies.

Answer 2

Explanation:

We know,

Interference of wave :

When two waves are superpose to form a resultant wave this condition is called interference of wave.

Waves interference are two types

(a). Constructive interference

The phase difference of the two waves is equal to an even multiple of $\pi$. It is called constructive interference

(b). Destructive interference

The phase difference of the two waves is equal to an odd multiple of$\pi$. It is called destructive interference

Beat frequency :

The difference in frequency of the node or antinode is equal to the beat frequency.

Answer:

So, we can say that when two waves of the different frequencies are superposed then beats generate.
