The phenomenon of beats occurs when tuning two musical instruments because...the Doppler shift affects one instrument but not the other.the two tones are interfering constructively and destructively with each other.the two tones only interfere constructively.the two tones only interfere destructively.

Given:

The phenomenon of beats occurs when tuning two musical instruments

To find:

The reason

Explanation:

Two waves with nearly the same frequencies and same amplitudes superimposed with each other produce beats. If an instrument is sounded against a standard frequency and tuned until the beats disappear then the instrument is in tune with the standard frequency. The tones interfere constructively and destructively with each other.

Hence, the second option is the correct one.
