Question 5

For the air/water interface in Questions 2 and 3, is there an angle for which the light reflected from the surface will be polarized.

Remember: the light is going from the air to the water and nair = 1 and nwater = 1.33.

Yes, total internal reflection will occur at any angle greater than 30 degrees.

No, Brewster's angle is only for light going from a higher index of refraction material to a lower index of refraction material.

No, total internal reflection only occurs for light going from a higher index of refraction material to a lower index of refraction material.

Yes, at Brewster's angle the light reflecting off the surface will be polarized in the plane of the surface. The angle between the reflected light and the transmitted light will be 90 degrees.

There is no relationship between index of refraction and the reflection and refraction of light, so there is not enough information to answer the question.

a.)

b.)

No, Brewster's angle is only for light going from a higher index of refraction material to a lower index of refraction material.

c.)
