Question

A flute is playing at a frequency of 800 Hz, and a second flute is playing along at 805 Hz. What is the frequency of the beat that is created?

Answer 1

5hz

Explanation:

The frequency of the beat when 2 sound waves of similar frequencies interfere is the difference between the 2 frequencies of the sounds waves.

`f_b= |f_1-f_2|`

`f_b=|800-805|=|-5|=5hz`
