What are three behaviors of light that cause it to be through of as a wave?

Reflection

refraction

interference

diffraction

Explanation:

The properties or behaviors of light that can be modeled as a wave are as follows:

Diffraction:

Light can bypass obstacles and diffuse out of slits, which is a property of waves.

Reflection:

light "bounces" when it comes across a smooth medium, that is, it returns to the original medium, this is also a characteristic of waves.

Refraction:

The path of light changes as it passes from one medium to another (also a property of waves).

Interference:

by superimposing two or more waves they influence each other, and the resulting light is the sum of the superimposed waves, which depending on their relative phases can cancel each other or increase the amplitude of the wave.

These are the characteristics of light that are explained with the wave model.
