A light ray strikes the perfectly smooth boundary between two different materials. The index of refraction of the material before the boundary is lower than that of the material after the boundary. On the basis of this information, the light ray will be

a. partially transmitted in a direction deviating more from the normal and partially reflected.

b. partially transmitted in a direction deviating less from the normal and partially reflected.

c. partially transmitted exactly in the same direction and partially reflected.

d. totally transmitted exactly in the original direction, without any reflection.

e. totally reflected in the first material, without any forward transmission.

A certain material has an index of refraction of 5/4. That means that in this material, as compared to a vacuum, light

a. travels at the same speed but has (4/5) of the frequency it would have in a vacuum.

b. travels with a speed (5/4) c and the frequency is the same it would be in a vacuum.

c. travels at the same speed but has (5/4) of the frequency it would have in a vacuum.

d. travels with a speed (4/5) c and has (4/5) the frequency it would have in a vacuum.

e. travels with a speed (4/5) c and the frequency is the same it would be in a vacuum.

1. What is the index of refraction of a material for which the
wavelength of light is 0.83 times its value in a vacuum?
2. A diffraction grating has 2400 lines per centimeter. At what
angle in degrees will the third-order maximum be for 636 nm
wavelength light?

We know that the index of refraction of materials can help identify those materials. A light beam is shined onto a surface a reflected ray and is found to be completely polarized when the angle of incidence is 56.5°, (a) What is the index of refraction of the reflecting material? (b) What is the angle of refraction if some light passes through the surface of the material?

The index of refraction in flint glass for these components of
white light - blue, yellow, and red colors are 1.639, 1.627, and
1.622 respectively. (a) Calculate, in nanometers, to four
significant figures, the wavelengths of these colors in flint glass
(b) During the time the blue light travels 1.000 m in flint glass,
the red light will travel (1) more than, (2) less than, (3) exactly
1.000 m. (c) Calculate the difference in the distance traveled by
the two...

If I have a light ray trapped between two very reflective
surfaces such that the light ray doesn't dissipate, how exactly can
I know that there IS a light ray there, without disturbing it? As
far as I understand, for me to actually observe the light
ray with my eyes means the light ray coming out of this loop
towards my eyes, escaping the loop. An easy way to test it I
suppose is to stick my hand in it...

An earthquake P wave traveling at 7.7km/s strikes a boundary within the Earth between two kinds of material.
If it approaches the boundary at an incident angle of 44? and the angle of refraction is 33?, what is the speed in the second medium?
Express your answer to two significant figures and include the appropriate units.

A costume jewelry pendant made of cubic zirconia is submerged in
oil. A light ray strikes one face of the zirconia crystal at an
angle of incidence of 29?
Once inside, what is the ray's angle with respect to the face of
the crystal? Note that the angle we need to find is complementary
to the refraction angle.

Use the exact values you enter to make later calculations.
A ray of light strikes a flat, 2.00-cm-thick block of glass
