How does light behave?

When light moves from one medium (like air) to another medium (like water) it will change directions. This is a "wave-like" behavior and is called refraction. In this way light behaves like other waves such as sound waves.

Answer: Light behaves like waves, they undergo reflection, refraction and diffraction just like any other wave would.

Explanation:

Light waves move and change direction all the time. But how can we compare them? to all other waves because this behavior happens constantly.
