Question

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, 42.7? and 57.3?. Find the indices of refraction in these two media.

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, 42.6? and 58.7?. Find the indices of refraction in...

A ray of light traveling through air strikes a piece of diamond
at an angle of incidence equal to 55.5 degrees.
Calculate the angular separation in degrees between the
red light and the violet light in the refracted ray, given
that:
The index of refraction of violet light ( Lamdaviolet = 400nm)
in diamond is 2.46.
The index of refraction of red light ( Lamdared = 700nm) in
diamond is 2.41.
Enter the numeric value in degrees.

A beam of light is traveling in air and strikes a material. The
angles of incidence and refraction are 65.1° and 42.7°,
respectively. Obtain the speed of light in the material.

A ray of light is traveling in glass and strikes a glass/liquid
interface. The angle of incidence is 58.0°, and the index of
refraction of glass is n = 1.50.
(a) What must be the index of refraction of the liquid such that
the direction of the light entering the liquid is not changed?
(b) What is the largest index of refraction that the liquid can
have, so that none of the light is transmitted into the liquid and
all...

A beam of light, traveling in air, strikes a plate of
transparent material at an angle of incidence of 56.0e. It is
observed that the reflected and refracted beams form an angle of
90.0e. What is the index of refraction of this material?

A beam of light is traveling through water(n=1.333). From there
it passes into a prism (n=2.750). If the incident angle is 53
degrees, what are the reflected and refracted angles? What would be
the critical angle between these 2 media?

True or False?
A)Reflection is the description of the portion of a ray of light
that remains in the medium from which it originated after striking
the boundary of a different medium.
B)Refraction refers to the change in direction of the ray of
light entering a new medium.
C)The angle of incidence equals the angle of refraction.
D)Angles in optics are measured with respect to the surface.
E)The intensity of the reflected beam is greater than the
intensity of the...

Sunlight strikes a piece of crown glass at an angle of incidence
of 30.3o. Calculate the difference in the angle of
refraction between a yellow (580 nm) and a violet (410 nm) ray
within the glass. The index of refraction is n=1.523 for yellow and
n=1.538 for violet light.
You have to calculate the angle of refraction for both light
rays (they have different indices of refraction). You are looking
for the difference of these angles.

The figure below shows the path of a beam of light through
several layers with different indices of refraction. (Assume
n4 = 1.10.)
An illustration shows four media, represented as long,
horizontal rectangles, arranged one on top of the other such that
each medium has a higher index of refraction than the medium below
it. The indexes of the four media from top to bottom are as
follows:
1.60,
1.40,
1.20,
and n4.
A ray of light starts from within...

A light ray in air, indicated by the arrow, is incident on a
convex glass lens at an angle of 31° to the normal. a) Some of the
light will be reflected from the lens. At what angle will it be
reflected? b) Find the angle at which the light ray is refracted
when entering the lens. (5 points) c) Find the angle at which the
ray is incident on the other side of the lens and the angle of...
