Mirror Math

The focal length is equal to the:

• radius of curvature
• diameter of curvature
• half radius of curvature
• half diameter of curvature

All rays that are parallel to the principle axis in a concave mirror reflects 

• Towards the focal point
• Away from the focal point
• Towards the center of curvature
• Away from the center of curvature

The following is a picture of what type of mirror? 

• Convex (diverging) mirror
• Concave (converging) mirror
• Plane Mirror
• Flat Mirror

Convex Mirrors produce...

• only virtual images
• virtual or real images
• only real images
• inverted images

An image that forms where light seems to come from a point but light rays don't actually meet is a 

• virtual image
• real image
• Inverted Image
• Pizza

What is the size and position of an image formed by a plane mirror?

• same size, closer to the mirror

• larger size, closer to the mirror

• same size, same distance away from the mirror

• reduced, farther from the mirror

Which terms describe the reflection seen in this image?

• virtual, upright
• virtual, inverted
• real, upright
• real, inverted
