Indexes of Refraction
Air or vacuum: 1.00 Water: 1.33
CR39: 1.498 Crown Glass: 1.523
Barium glass: 1.60 Flint glass: 1.70
Polycarbonate: 1.586 Diamond: 2.45
1. A ray of light traveling from air into crown glass strikes the surface at an angle of 30 degrees. What will the angle of refraction be?
2. Light traveling through air encounters a second medium which slows the light to 2.7 x 108m/s. What is the index of the second medium?
3. Light travels through a substance at 1.97 x 108 m/s. What is the index of the liquid? What type of liquid is it?

4. What is the index of refraction of a refractive medium if the angle of incidence in air is 30 degrees and the angle of refraction is 15 degrees?
5. If the angle of incidence of light traveling through air, striking water, is 30 degrees, what is the angle of refraction?
6. If the index of refraction for a certain glass is 1.50, and the angle of refraction is 15 degrees for a ray of light traveling from air, what is the angle of incidence?
7. What is the velocity of light in meters per second in a material with an index of 2.0?
8. A light ray moving through CR39 at an angle of 49 degrees exits into another medium at an angle of 27.48 degrees. What is the index of the second medium? What is this medium?
9. If the incoming angle from the air is 20o from the normal.
a. What angle is light traveling through each of the mediums below:
i. Flint glass:
ii. Water:
iii. Diamond:
iv. Cubic Zirconium:
v. Air:
b. How does the final angle of the light in air compare to the initial angle of light in air?

Answer 1

Answer:

name ahould be Snell law

Explanation:

snwll law is about refraction and tells that it's is constant
