Question

Two waves with equal amplitude meet each other, resulting in a wave zero amplitude. Which phenomenon explains this result?
A.) diffraction
B.) Reflection
C.) Refraction
D.) Interference

Answer 1

Answer:

(D) Interference

Explanation:

Interference is a phenomenon characteristic for waves. When two waves meet, they interfere and result in a new wave. The precise shape of the resultant wave depends on the amplitude, frequency and phase of the constituent waves. In a most basic setting, two types of interference occur: constructive (resultant amplitude increases) and destructive (resultant amplitude decreases).
