Reflection and Refraction

If the angle of incidence is 45 degree, what is the angle between the incident ray and reflected ray

• 45
• 90
• 180
• none of the above

In the given figure , which angle represents angle of incidence ?

• a

• b

• c

• d

Why does the lower part of the child appear so much different in size from the upper part?

• The light rays that travel through water and then into air are refracted.
• The light rays that travel through water and then into air are enlarged.
• The light rays that travel through air and then into water are reflected.
• The light rays that travel through air and then into water are reduced.

In the diagram, which letter represents the reflected ray?

• A

• B

• C

• D

Which is the reflected ray?

• A

• B

• C

• D

When light passes from air to water, what happens to the speed of the light?

• speeds up

• slows down

• stays the same

How does light behave as it enters these mediums?

• continue its path as straight line.
• bends toward the normal
• bends away from the normal
• reflects

Which is the angle of refraction?

• Angle 1
• Angle 2

Swimming pools and the ocean look shallower than they really are due to:

• reflection 
• dispersion
• refraction
• total internal reflection

A ray of light hits a plane mirror. Using the diagram determine the angle of reflection, r.
