What is required for the refraction of light?
3-5A
What is required for the refraction of light?
The light must change speed.
3-10If light slows down entering a material, does it refract towards
or away from the normal?
3-10AIf light slows down entering a material, does it refract towards
or away from the normal?
Towards
3-15Draw the path of the light as it moves through and out of these materials:
(Show normal lines)
n = 1.5 n = 1.0 n = 2.5
3-15ADraw the path of the light as it moves through and out of these materials:
(Show normal lines)
n = 1.5 n = 1.0 n = 2.5
3-20What happens if light strikes a surface beyond the ‘critical angle’?
3-20AWhat happens if light strikes a surface beyond the ‘critical angle’?
Total internal reflection
3-25When light enters a medium with a higher index of refraction, the speed of
light decreases. The change in what property of a light wave causes this?

λ
4-5What is Snell’s Law?
4-5AWhat is Snell’s Law?
n1sin(θ1) = n2sin(θ2)
4-10What is the index of refraction for a material in which the speed of light is
0.2C?
4-10AWhat is the index of refraction for a material in which the speed of light is
0.2C?
n = C/V
V = 0.2C
n = C / 0.2C
n = 5
4-15The light below travels from water to air. At what angle will the light travel
in the air?
20°
4-15A
nwater = 1.33 nair = 1
(nwater)sin(θwater) = (nair)sin(θair)
1.33sin20 = 1sin(θair)
θair = 27°
The light below travels from water to air. At what angle will the light travel
in the air?
4-20Type Question Here
4-20A
Light travels from crown glass (n = 1.52) into diamond (n = 2.42). If the angle of refraction
is 15°,what was the angle of incidence?
(nglass)sin(θglass) = (ndiamond)sin(θdiamond)
1.52sin(θglass) = 2.42sin(15°)
θglass = 30°
4-25What is the critical angle of a light ray that is travelling from the Goron’s
Ruby (n = 3.6) to air?
4-25A
(nruby)sin(θc) = (nair)sin(90°)
3.6sin(θc) = 1*1
θruby = 16.1°
What is the critical angle of a light ray that is travelling from the Goron’s
Ruby (n = 3.6) to air?
