Review of Reflection and Refraction of Light

Review of Reflection and Refraction of Light. Finchum Physics 2013. Reflection of Light. Reflection = Bouncing Occurs when medium is opaque Angle of incidence is equal to angle of reflection. All angles occur with respect to ( wrt ) the normal (perpendicular). Refraction of Light.
