What happens to the amplitude of the resultant wave when two sound waves with equal amplitude constructively interfere?

The amplitude of the resultant wave will be twice the amplitude of each wave

Explanation:

- Constructive interference occurs when two waves meet in phase (, which means that the crest of a wave meets the crest of the other wave: in this case, the amplitude of the resultant wave is the sum of the amplitudes of the single waves

- Destructive interference occurs when the two waves meet in anti-phase (, which means that the crest of a wave meets the trough of the other wave: in this case, the amplitude of the resultant wave is the difference between the amplitudes of the single wave

In this problem, we have constructive interference between the two waves: this means that the resultant amplitude is the sum of the two waves. Since the two waves have equal amplitude (we can call it A), the resultant amplitude will be

so, twice the amplitude of the single wave.

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.
