What does a ray diagram of the law of reflection show?

A mirror with a flat surface is known as a(n) __________.

• plane mirror

• concave mirror

• convex mirror

• spherical mirror

Identify the properties of plane mirrors. (Mark all that apply.)

• Plane mirrors always produce virtual images.

• Plane mirrors produce right-left reversed images of objects.

• Light rays reflect from a mirror at an angle that is twice as large as the angle of incidence.

• Your image appears to be the same distance behind a mirror as you are in front of it.

What type of image is a copy of an object formed at the location from which the light rays appear to meet, but don't actually meet?

• reversed image

• virtual image

• real image

• reflected image

Identify the object that is most like the shape of a concave mirror.

• the inside of a shallow bowl

• the bottom of a bucket

• the outside surface of a ball

• a glass window pane

The point at which light waves meet is called the ______.

• real point.

• virtual point.

• optic point.

• focal point.

Is the following sentence true or false? A real image is a copy of an object formed at the point where light rays actually meet.

• True

• False

A curved mirror whose outside surface is the reflecting surface is called a(n) ________ mirror.

• convex

• concave

• plane

• spherical
