Answer to Question #164075 in Physics for Joshua

Question

Suppose a two sound source emitted a slightly different sound frequency, 262Hz ans 266 Hz, were released at the same time. Determine the beat frequency and frequency heard by the observer.

What are the given;

First Frequency (F1)    F1= 262 Hz

Second Frequency (F2)  F2= 266 Hz

What are the missinv:  

Beat Frequency       Fb= ?

Perceived Frequency   Fo=?

Answer 1

Beat Frequency

$$f_B=266-262=4\ Hz$$

Perceived Frequency

$$f_o=0.5(266+262)=264\ Hz$$
