Total Internal Reflection Conceptual Question?

Question

Consider scenarios A to F in which a ray of light traveling in material 1 is incident onto the interface with material 2.

Part B
For the scenarios in which total internal reflection is possible, rank the scenarios on the basis of the critical angle, the angle above which total internal reflection occurs. At this angle, the refracted ray is at 90deg from the normal.
Rank from largest to smallest. To rank items as equivalent, overlap them.

the scenarios are:

n1, diamond = 2.42
n2, water = 1.33

n1, diamond = 2.42
n2, air = 1.00

n1, benzene = 1.50
n2, water = 1.33

n1, water = 1.33
n2, air = 1.00

Answer 1

1.33/2.42 = 0.550

1.00/2.42 = 0.413

1.33/1.5 = 0.887

1.00/1.33 = 0.752



For angles from 0 to 90 degrees, a larger angle always has a larger sine,

so the benzene-water combo has the largest critical angle, the water-air

combo is next, the diamond-water combo is next, and the diamond-air

combo has the smallest critical angle.

Answer 4

when a light ray passes from a denser medium to a rarer medium the light ray is bend away from the normal. So if we go on increasing the angle of incidence then there will be a point when light ray will travel on the boundary of the two media. This angle is called critical angle. Now if we increase the angle greater than critical angle then light ray travels inside the same medium and hence it is totally internally reflected. This all depends on the refractive indices of the materials.
