Answer:

F. Either B or C

Explanation:

The beat frequency is the difference of two frequencies of two waves.

Here, one wave has frequency 610 Hz and the beat frequency is 3 beats per second.

It is not mentioned which has a higher frequency. So, there are two possiblities.

[tex]\Delta f=|610-613|=3[/tex]

or

[tex]\Delta f=|610-607|=3[/tex]

Hence, the frequency of the other wave is 613 or 607.
