Reflection and Refraction

Question 1

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

Revolt · Accepted Answer

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

Question 2

An incident ray of light strikes water at an angle of 30°. The index of refraction of air is 1.0003, and the index of refraction of water is 1.33.

Revolt · Accepted Answer

22°

Question 4

Kayla drew two ray diagrams to compare the behavior of light rays.

Revolt · Accepted Answer

Diagram X shows refraction from a denser to a less dense medium, and diagram Y shows reflection.

Question 5

A ray diagram is shown.

Revolt · Accepted Answer

It shows the ray passing through the boundary.

Question 6

A ray diagram is shown.

Revolt · Accepted Answer

The diagram shows refraction, and medium 1 is less dense than medium 2.

Question 7

A ray diagram for a refracted light ray is shown.

Revolt · Accepted Answer

normal

Question 8

Serena draws a diagram to compare what happens when rays hit a boundary and are either reflected or refracted.

Revolt · Accepted Answer

X: ray bounces off a boundary and maintains constant speed Y: ray changes direction Z: ray passes through a boundary and changes speed

Question 9

Which are characteristics of a ray when it hits a boundary and refracts, but not when it hits the boundary and reflects? Check all that apply.changes direction changes speeddoes not change directiondoes not change speed bounces off the boundarypasses through the boundary

Revolt · Accepted Answer

changes speed; passes through the boundary
