Homework Answers
When light travels from a rarer medium to a denser medium, it bends towards from the normal.
When light travels from a denser medium to a rarer medium, it bends away from the normal.
4) option is correct
a) When light travels from a rarer medium to a denser medium, it bends towards from the normal.
b) When light travels from a denser medium to a rarer medium, it bends away from the normal.
Figure
(4) is correct because in (a) it bents towards normal while going
from rarer to denser medium.In (b) it goes away from from the
normal while going from denser to rarer medium.

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...

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?

An incident coherent light ray strikes the interface between two different media with indices of refraction...
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...

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) 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
the rays.

Find the intensity of reflected and transmitted waves through an interface between two linear non-conducting media...
Find the intensity of reflected and transmitted waves through an interface between two linear non-conducting media in terms of the intensity of the incident wave and the indices of refraction of the two media. Note: To do this, suppose a plane wave of frequency ω and electric field polarization in the x direction is traveling in the positive z direction. The wave approaches the interface between two media on the xy plane from left. Write complex waves equations for the...

A ray of light travels through air until it strikes the interface between the air and another medium. The incident ray makes an angle of - 48.0° with the normal, as shown in the figure below. Upon passage into the second medium, the ray is refracted, emerging from the interface at an angle 0, with respect to the normal. e Air Second medium (a) Suppose that the second medium is Ice. What is the angle of refraction, 02 (in degrees)?...
