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 when entering a new medium, not related to wave collision energy increase.
• Reflection is the bouncing back of waves, not about energy increase from collision.
• Constructive interference occurs when waves collide in - phase, resulting in a wave with greater amplitude (and thus increased energy as energy is related to amplitude).
• Destructive interference occurs when waves collide out - of - phase, resulting in a wave with reduced amplitude (decreased energy).

Answer:

C. constructive interference
