What happens when light waves hit a surface?.  The Law of Reflection from a flat surface states that the angle of incidence is ALWAYS equal to the angle.

Topic 5 Reflection of Light Light has particle characteristics and behaves like waves. It is a member of the electromagnetic spectrum.

The incident ray and the reflected ray behave in predictable ways, which leads to the two laws of reflection: 1.The angle of incidence equals the angle.

PLANE MIRROR REFLECTION Law of Reflection – the angle of the incident light ray is equal to the angle of the reflected light ray.

Plane Mirrors Hold the mirror 20 cm from your face. How far into the mirror is your reflection?

The reflection is behind the mirror. A virtual image appears in a location where the light doesn’t really reach.

Virtual Images in Plane Mirrors Image is the same distance behind the mirror as the object is in front of it. Image and object are the same size.
