Reflection

Vocabulary:

• Incident ray: light ray travelling towards reflecting surface

• Reflected ray: light ray that has bounced off reflecting surface

• Normal: perpendicular line to surface (Invisible)

• Angle of incidence (i): angle between incident ray & normal

• Angle of reflection (r): angle between reflected ray & normal

Laws of Reflection:

• The angle of reflection (r) is equal to the angle of incidence (i)​

• The reflected ray and the incident ray are on opposite sides of the normal​

• The incident ray, the normal, and the reflected ray lie on the same plane (flat surface)​
