Question

Two tuning forks having frequencies of 460 and 464 Hz are struck simultaneously. What average frequency will you hear, and what will the beat frequency be?

a) 462 Hz, 4 Hz
b) 460 Hz, 2 Hz
c) 464 Hz, 4 Hz
d) 462 Hz, 2 Hz

Answer 1

When two tuning forks with frequencies 460 Hz and 464 Hz are struck simultaneously, you will hear an average frequency of 462 Hz and a beat frequency of 4 Hz.

Step-by-step explanation:

When two tuning forks with frequencies 460 Hz and 464 Hz are struck simultaneously, you will hear an average frequency of 462 Hz. The beat frequency is the difference between the two individual frequencies, so in this case, the beat frequency would be 4 Hz.
