Reflection

_____ reflection occurs when light reflects off a rough surface and forms a blurry image or no image at all.

• Diffuse

• Total

• Zero

• Internal

Which is the incident ray?

• A

• B

• C

• D

____________________ reflection occurs when light reflects off a very smooth surface.

• Diffuse

• Total

• Regular

• Internal

The angle of incidence and angle of reflection are measured relative to the ____________________ line.

• Normal

• Regular

• Vertical

• Angular

If the reflecting surface is a very ____________________ surface, the reflection will be regular, meaning the light rays maintain their position relative to each other.

 

• rough

• regular

• smooth

• irregular

Which law states that the angle at which light rays reflect off a surface is equal to the angle at which the incident rays strike the surface?

• Law of Refraction

• Law of Incidence

• Law of Diffusion

• Law of Reflection

The law of reflection states that, when a light ray strikes a reflecting surface, the angle of incidence (measured from the normal line) is equal to the angle of reflection (also measured from the ___________).

• diffusion surface

• reflection surface

• normal line

• reflecting line

In a plane mirror, while the left and right of the image are reversed, the ________________ of the image are not.

• inverses

• top and bottom

• sides

• planes

If the reflecting surface is rough, the reflection will be diffuse and objects will be _________________ in the reflection.

• invisible

• inverted

• distorted

• reflected

If the reflecting surface is a very smooth surface, the reflection will be regular, in which the light rays __________ their position relative to each other.

• maintain

• reverse

• invert

• are perpendicular in
