1.
 Speed and Refraction
a) If fused quartz is faster?
D
(angle of refraction < angle of incidence)
c) Fused quartz same speed as Medium X
C
(No bending)
d) This ray is not possible
A
(light always crosses over normal)
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 > Velocity of Water
If
θin = 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

Find the missing ray in
the ray diagram below

The reflected ray at
the glass/air
boundary
is missing.

Did you know....
A sunset is an optical
illusion !!!
Refraction allows you
to see the
sun
even after it has set.
|
Which ray diagram is correct?
Choice 2
(Angle ray leaves air = Angle ray enters
air)
At what angle will the ray reenter the air?
June 2008 #72
35 degrees

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

When a wave enters another medium,
part of the wave is
transmitted, part is
reflected.
