Question

Two tuning forks are struck at the same time. One tuning fork has a frequency of 425 Hz. The beat frequency of the resulting sound is 4 Hz. What are the two possibilities for the frequency of the other tuning fork?

Answer 1

The beat frequency between two tuning forks is the difference between their frequencies. In this case, we have a tuning fork with a frequency of 425 Hz and a beat frequency of 4 Hz. The possible frequencies of the other tuning fork are 429 Hz and 421 Hz.

Step-by-step explanation:

The beat frequency between two tuning forks is the difference between their frequencies. In this case, we have a tuning fork with a frequency of 425 Hz and a beat frequency of 4 Hz. The beat frequency between two tuning forks is the difference between their frequencies.

In this case, we have a tuning fork with a frequency of 425 Hz and a beat frequency of 4 Hz. The possible frequencies of the other tuning fork are 429 Hz and 421 Hz. To find the possible frequencies of the other tuning fork, we can add or subtract the beat frequency from the given frequency:

Possible frequency 1: 425 Hz + 4 Hz = 429 Hz

Possible frequency 2: 425 Hz - 4 Hz = 421 Hz
