using snell's law
sin50 / sin45 = nb / 1.2
1.0833 = nb / 1.2
nb = 1.0833 X 1.02
nb = 1.105
and
sin45 / sin56.7 = nc / nb
0.846 = nc / 1.105
nc = 0.846 X 1.105
nc = 0.934
so the indices are nb = 1.105 and nc = 0.934

The drawing shows a ray of light traveling through three
materials whose surfaces are parallel to each other. The refracted
rays (but not the reflected rays) are shown as the light passes
through each material. A ray of light strikes the
a–b interface at a 50.0˚ angle of incidence. The
index of refraction of material a is
na = 1.20. The angles of refraction in
materials b and c are, respectively, 44.0˚ and
53.5˚. Find the indices of refraction in...

At an interface between an unknown transparent materials and water, a ray of light is incident from the water side at an angle of 45 degree to the normal. The refracted ray makes an angle of 36.8 degree with the normal. A) What is the index of refraction for the unknown materials? B) what is the critical angle for total internal reflection for the interface described? C) make a drawing showing the geometry for rays that would undergo total internal reflection...
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...
A light ray propagates in a material with index of refraction 1.15, strikes an interface, and passes into a material whose index of refraction is 1.33. The angle of incidence at the interface is 26.7 degree. Find the angle of refraction. theta = Number ______ degree
The drawing shows a ray of light traveling from point A to point B, a distance of 6.40 m in a material than has an index of refraction n1. At point B, the light encounters a different substance whose index of refraction is n 1.63. The light strikes the interface at the critical angle of c-40.9°. How much time does it take for the light to travel from A to B? 21.63 Number Units
At an interface between an unknown transparent material and water, a ray of light is incident from the water side at an angle of 30.0 degrees to the normal. The refracted ray makes an angle of 25.0 degrees. A) what is the index of refraction for the unknown material? B) what is the critical angle for total internal reflection for the interface described?

Light of wavelength 500nm traveling in air is incident along the
normal on Face A of a 60-60-60 glass prism of refractive index
1.52, as shown in the figure.
a) The refracted ray is incident to Face B. Calculate the angle
of incidence of the ray, the angle of refraction of the refracted
ray (if any) and the angle of reflection of the reflected ray. Draw

An incident coherent light ray strikes the interface between two different media with indices of refraction n1 and n2 (see figure below). Part of the ray gets reflected, and part of the ray gets refracted. Based on the information shown in the figure, which of the following is true? Let v1 and v2 be the speed of light in media 1 and 2, respectively. v1 < v2 v1 = v2 The reflected ray undergoes no phase shift relative to the...
Here is a figure that shows a light ray that is H=23cm parallel
to and above the ground.
The light ray goes through a medium with an index of refraction
of n1=1.2, and some of it reflects and some of it
refracts.
The refracting part goes into a medium with an index of
refraction of n2=1.5.
If the angle ? = 30 degrees:
What is the distance between point A and point B (in
cm)?
What is the angle between...
