Question

which situation would result in interference?
a wave bouncing off an object
a wave bending as it moves through an object
a wave scattering as it moves through an object
a wave increasing in energy as it hits another wave

Explanation:

Interference occurs when two or more waves interact. When a wave increases in energy as it hits another wave, this is an interaction between waves which is interference. Bouncing is reflection, bending is refraction, and scattering is a different - type of wave - matter interaction.

Answer:

a wave increasing in energy as it hits another wave
