Chapter 12.3. Reflection and Color. Angle of Reflection = Angle of Incidence. Balls bouncing on a pool table follow laws of reflection. Rough surfaces reflect light in many directions, called DIFFUSE REFLECTION. When the water is still, reflection is “ clearer ”.
Reflection and Color
White light strikes the apple
All colors absorbed except red
Red light is reflected
Green light strikes the apple
Green light is absorbed. No color is reflected so apple appears black
The critical angle for diamondin air is 24.5 degrees; any raywhich strikes the surface on theinside at an angle of greaterthan 24.5 degrees will notescape the diamond.
