Question

What beat frequency will occur when a 370-hz and a 374-hz sound source are sounded together?

Answer 1

4Hz

Step-by-step explanation:

The beat frequency is generated when two waves with frequencies f1 anf f2 are joint together. The frequency of the beat is given by:

`f_b=|f_1-f_2|`

fb: frequency of the beat

f1, f2: frequencies that joint generate a pulse with frequency fb.

By replacing you obtain:

`f_b=|374Hz-370Hz|=4Hz`

hence, the frequency of the beat is 4Hz

Answer 2

4 Hz

Step-by-step explanation:

Parameters given:

Frequency of first sound , F1 = 370 Hz

Frequency of second sound, F2 = 374 Hz

Beats are a series of fluctuations that are caused by the interference of two waves with similar frequencies.

Beat frequency is given mathematically as:

Fb = | F1 - F2 |

Beat frequency is always positive.

Therefore, the beat frequency is:

Fb = | 370 - 374 | Hz

Fb = | -4 | Hz

Fb = 4 Hz
