Question

what is the difference between Beats and interference?

Answer 1

1. The difference of frequencies is almost equal.

2. Phase difference of two waves with respect to time is constant.

3. The resultant amplitude with respect to time is not constant and it is ,

4. The resultant frequency is the average of two frequencies.

Interference:

1. The difference of frequencies is equal.

2. The phase difference of two waves with respect to time is not constant.

3. The resultant amplitude with respect to time is constant and it is

4. The resultant frequency is equal to each of the frequency.
