Answer:
4 Hz
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
Answer:
4Hz
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:
[tex]f_b=|f_1-f_2|[/tex]
fb: frequency of the beat
f1, f2: frequencies that joint generate a pulse with frequency fb.
By replacing you obtain:
[tex]f_b=|374Hz-370Hz|=4Hz[/tex]
hence, the frequency of the beat is 4Hz
