Final answer:
The two types of interference are constructive and destructive interferences. The correct answer is a) True
Step-by-step explanation:
The correct answer is a) True. The statement that the two types of interference are constructive and destructive interferences is indeed true. Constructive interference occurs when two waves combine to create a wave with a larger amplitude, while destructive interference occurs when two waves combine to create a wave with a smaller amplitude. Conversely, destructive interference occurs when two or more waves combine to produce a wave with a smaller displacement, or even cancel each other out.
Constructive interference happens when the crest of one wave overlaps with the crest of another, leading to a higher amplitude. On the other hand, destructive interference happens when the crest of one wave aligns with the trough of another, which can lead to a reduced amplitude or complete cancellation. These principles are fundamental in the study of wave behavior and have various applications in fields such as acoustics, optics, and electronics.
