Question

Derive an expression for beat frequency of two sounds of same intensity

Answer 1

Answer:

The beat frequency is always equal to the difference in frequency of the two notes that interfere to produce the beats. So if two sound waves with frequencies of 256 Hz and 254 Hz are played simultaneously, a beat frequency of 2 Hz will be detected.

Explanation:

obtain an expression for the beat frequency when two wavesof frequenciesv1 and v2 overlap. Beats is a common physical phenomena which refers to the interference of two waves of slightly different frequencies which results in a peculiar waveform which is a periodic variation of both amplitude and frequency.

Actually, the beat frequency is the complete value of the difference in wave frequencies. The formula for the beat frequency is, Where the frequency of two waves are f1 and f2 .
