Light travels from material #1 with refractive index
n1 and incidence angle θ1 into
material #2 with refractive index n2 and
refraction angle θ2. Choose the correct
statement below.
If θ1 < θ2, then material #1 has a smaller
index of refraction.
If θ1 > θ2, then material #1 has a larger
index of refraction.
If θ1 > θ2, then material #1 has a smaller
index of refraction.
If θ1 < θ2, then light travels slower in
material #2.
If θ1 < θ2, then material #2 has a larger
index of refraction.
By Snell’s law,
n1sinθ1 = n2sinθ2
n2 = n1*(sinθ1/sinθ2)
If, θ1 > θ2 => sinθ1/sinθ2 > 1
Gives, n2 > n1
It means, material #1 has smaller index of refraction.
If, θ1 < θ2 => sinθ1/sinθ2 < 1
Gives, n2 < n1
It means, material #1 has larger index of refraction.

(a) Briefly explain what is meant by the following terms: refraction, refractive index, angle of incidence, angle of refraction. [4 marks] (b) The drawing shows four different situations in which a light ray is traveling from one medium into another. In some of the cases, the refraction is not shown correctly. For cases (i), (ii), and (iii), the angle of incidence is 55°; for case (iv), the angle of incidence is 0°. Identify which cases are incorrectly drawn and determine...

water interface (the surface of the lake), it is partly reflected back into the air and partly refracted or transmitted into the water. This explains why on the surface of a lake sometimes you see the reflection of the surrounding landscape and other times the underwater vegetation. These effects on light propagation occur because light travels at different speeds depending on the medium. The index of refraction of a material, denoted by n, gives an indication of the speed of...
