Question

Wave A has an amplitude of 2, and wave B has an amplitude of 2. What will happen when the crest of wave A meets the trough of wave B?

They will interfere to create a crest with an amplitude of 0.
They will interfere to create a crest with an amplitude of 2.
They will interfere to create a crest with an amplitude of 4.
They will bounce off each another.

Answer 1

In this particular case, since the amplitudes of the waves, are not on sync with each other, as stated that the crest of the first wave meets the trough of the second wave, the amplitudes knowing that are the same would cancel out.

They will interfere to give a crest with an amplitude of 0.

Answer 2

Answer:

Sample Response: No, the resulting wave in the diagram does not demonstrate destructive interference. The resulting wave in the diagram shows a bigger wave than Wave 1 or Wave 2. If it demonstrated destructive interference, it would be a smaller wave or a horizontal line. With destructive interference, waves break down to form a smaller wave, or cancel each other out, resulting in no wave formation.
