Y10 Light Revision

Which letter best represents the angle of incidence?

• A

• B

• C

Which letter best represents the angle of reflection

• A

• B

• C

Which letter best represents the normal line?

• A

• B

• C

If the angle of incidence in the diagram is 50 degrees, which statement is true?

• The angle of reflection is 40 degrees because is is measured from the normal line, which is 90 degrees

• The angle of reflection is 50 degrees because it is equal to the angle of incidence.

• The angle of reflection is 60 degrees, because it is greater than the angle of incidence.

• The angle of refraction is 50 degrees, because it is equal to the angle of incidence.

Select all statements that are true.

• Sunlight is all colors, but appears white.

• White light is a combination of all colors of light.

• White light has no colors of light.

• A spectroscope will separate white light so you can see all the colors.
