Question

pierce conducts an experiment in which waves collide in a way that the energy increases. what has occurred?
refraction
reflection
constructive interference
destructive interference

Explanation:

Refraction is the bending of waves, reflection is the bouncing - back of waves. Constructive interference occurs when waves combine to increase amplitude and energy. Destructive interference decreases amplitude and energy. Since the energy increases in Pierce's experiment, it is constructive interference.

Answer:

C. constructive interference
