Question

two Sound Waves Traveling In The Same Medium Interfere With Each Other. The Compression Of One Wave Falls On The Compression Of The Other Wave. What Can You Say About The Resultant Sound?

Answer 1

You can't say anything about them unless their frequencies are the same.
In that case, you've already said that they're in phase, so their interference
is constructive. The resultant sound is louder than either wave alone. If their
amplitudes also happen to be the same, then the resultant sound is double
the intensity of either one alone (6 dB louder).

Answer 2

Answer:

A

Explanation:

Because no sound is heard.
