C. Refraction – the bending of light that occurs when a light wave passes through a boundary between two media

Refraction - St. Mary's H.S. Physics

1. Speed and Refraction

If fused quartz is faster?

If Light goes from fast medium to slow, light bends toward the normal
 

Slow medium to fast, light bends away from the normal

Light Ray leaving water  and entering Air

Velocity of Air is greater than the Velocity of Water

 
If θ_in = 0 degrees,
no refraction
 

Light must come in at
an angle to be refracted

Which medium is faster?

Medium A
(larger angle from normal) 

REFRACTION IS ALWAYS ACCOMPANIED BY REFLECTION

Refraction - David M. Harrison

A sunset is an optical illusion !!!!

reenter the air?
