1.
Speed and Refraction
a) If fused quartz is faster?
![](img48B.jpg)
D
(angle of refraction < angle of incidence)
![](img48B1.jpg)
c) Fused quartz same speed as Medium X
![](img48B1.jpg)
C
(No bending)
![](img48B1.jpg)
d) This ray is not possible
![](img48B1.jpg)
A
(light always crosses over normal)
![](img48B1.jpg)
If Light goes from fast medium to
slow, light bends toward the normal
![](img90.gif)
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
|
![](img97.jpg)
(Light must come in at
an angle to be refracted)
Which medium is faster?
![](img4E.gif)
Medium A
(larger angle from normal)
REFRACTION IS ALWAYS
ACCOMPANIED BY REFLECTION

Find the missing ray in
the ray diagram below
|
![](../../geekQuestion.gif) |
The reflected ray at
the glass/air
boundary
is missing.

Did you know....
A sunset is an optical
illusion !!!
![](img52.gif)
Refraction allows you
to see the
sun
even after it has set.

Which ray diagram is correct?
![](img5A.gif)
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?
![](img10.gif)
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.
