Reflection and Refraction - Quiz Quiz

Question 1

Rays of light strike a bumpy road and are reflected. What can be predicted about the reflected rays?

Revolt · Accepted Answer

B: Each will reflect at an angle equal to its angle of incidence.

Question 2

A ray of light strikes a smooth surface and is reflected. The angle of incidence is 35 degrees What can be predicted about the angle of reflection?

Revolt · Accepted Answer

A: Rays will follow the law of reflection, so the angle of reflection will be  35 degrees .

Question 3

An incident ray of light strikes water at an angle of 30 degrees The index of refraction of air is 1 point 0 0 0 3 , and the index of refraction of water is 1 point 3 3 What is the angle of refraction rounded to the nearest whole number?

Revolt · Accepted Answer

B: 22 degrees

Question 4

Question 7

Rays of light strike a bumpy road and are reflected. What can be predicted about the reflected rays?

Revolt · Accepted Answer

D: Each will reflect at the exact same angle of reflection.

Question 8

An incident light ray strikes water at an angle of 20 degrees. The index of refraction of air is 1 point 0 0 0 3 , and the index of refraction of water is 1 point 3 3

15

Question 9

Which statement describes how rays behave when they travel through media during reflection and refraction?

Revolt · Accepted Answer

A: During reflection, rays stay in the original medium, and during refraction, rays pass into a new medium.
