• inward

• outward

Store security mirrors and rear view mirrors are both examples of

• concave mirrors

• convex mirrors

The law of reflection states that when light rays strike a plane mirror they are

• reflected at the same angle at which they arrived

• reflected at a larger angle at which they arrived

The line that passes through the center of a curved mirror is called

• focal point
• center of curvature 
• principle axis
• light ray

The distance between the focal point and the mirror is

• raduis
• diameter
• focal point
• focal length

• Real Image
• No Image

Compared to the object in front the lens, its image is.....

• Virtual, upright, smaller
• Real, inverted, larger
• Real, inverted, smaller
• Virtual, upright, larger

In the formula m = hi/ho, the variable "m" refers to ___.

• the height of the image
• the height of the object

• how reduced or enlarged the image is compared to the object
