Speed and Refraction
a) If fused quartz is faster?
(angle of refraction < angle of incidence)
c) Fused quartz same speed as Medium X
d) This ray is not possible
(light always crosses over normal)
If Light goes from fast medium to
slow, light bends toward the normal
Slow medium to fast,
away from the normal
||Light Ray leaving water
and entering Air
Velocity of Air > Velocity of Water
θin = 0 degrees,
(Light must come in at
an angle to be refracted)
Which medium is faster?
(larger angle from normal)
REFRACTION IS ALWAYS
ACCOMPANIED BY REFLECTION

Did you know....
A sunset is an optical
Refraction allows you
to see the
even after it has set.
Which ray diagram is correct?
(Angle ray leaves air = Angle ray enters
At what angle will the ray reenter the air?

What's wrong with this picture?
Air is faster than flint glass. second angle should
