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 meet. When a wave increases in energy as it hits another wave, this is constructive interference (a type of interference). A wave bouncing off an object is reflection. A wave bending as it moves through an object is refraction. A wave scattering as it moves through an object is scattering.

Answer:

a wave increasing in energy as it hits another wave
