Question

Ari and Martin are playing with tuning forks. Ari pulls out a tuning fork with an unknown frequency and hits it at the same time that Martin strikes a tuning fork with a frequency of 440 Hz. What are the possible frequencies of Ari's tuning fork? a) 440 Hz or 430 Hz Jay b) 4.4 Hz or 4.3 Hz. c) 443 Hz or 437 Hz d) There is not enough information to determine this answer

Answer 1

d) There is not enough information to determine this answer

Explanation:

Given:

Frequency 1 (f1) = 440 Hz

We have the following:

`beats=∣f_1-f_2|`

We don't know the beats, therefore we can't determine the missing frequency.

This means that the correct answer is d) There is not enough information to determine this answer
