Reflections and Mirrors Lesson Check

A sharp image is formed when light reflects from a ________________surface.

• rough

• smooth

• absorbent

• black

The reflection of light waves from a rough surface is ______________reflection.

• confused

• diffuse

• transfused

• refused

You can see yourself in a mirror because light ________________ off of the surface of a mirror

• absorbs

• reflects

• transmits

• transfers

An image that forms where rays converge is a(n) ________________ image. (sometimes inverted)

• fake

• real

• virtual

• imaginary

What is the center, dashed line, perpendicular

to the mirror surface, called?

• Neutral

• Nuclear

• Normal

• Abnormal

Give an example

of a phenomenon

that results in the

scattering of light.

• Brownian motion

  (Dust particles in the air)

• Clouds

The object in a plane mirror can be upright OR inverted depending on where the object is.

• True

• False

Answer explanation

The image will be upright in a plane mirror.

If the angle of incidence ( Angle I ) increases,

the angle of reflection ( Angle R ) will ______________.

• remain the same

• decrease by the same amount

• increase by the same amount

• decrease to zero

How are diffuse reflections different than regular reflections?

• there is no difference

  diffuse reflections make a sharp image

• diffuse reflection are at

  irregular angles, blurring images

When parallel light rays strike a convex mirror, they converge (or come together).

• False,

  Convex makes

  rays reflect outward, or diverge.

• True,

  Convex mirrors

  focus light together,

  just like concave mirrors.
