Two tuning forks sounding together result in a beat frequency of 4 Hz.If the frequency of one of the forks is 252 Hz,what is the frequency of the other?

Question

Quizplus · Accepted Answer

Let the frequency of the other tuning fork be x Hz. Then the beat frequency is given by the absolute difference of the frequencies of the two forks i.e. |252-x|. We are given that the beat frequency is 4 Hz. Therefore |252-x|=4. Solving this equation gives us x=248 or x=256. Hence the frequency of the other fork is either 248 Hz or 256 Hz. Therefore, the correct choice is C).
