According to the Law of reflection, a light ray striking a mirror

• continues moving through the mirror in the same direction
• moves into the mirror at a slightly different angle
• bounces off the mirror toward the direction it came from
• bounces off the mirror at the same angle it hits.

Why do you not see an image when light reflects off a rough surface?

• because not enough light is not reflected
• because the reflection is regular
• because the reflection is diffuse
• because the law of reflection does not apply

An image that you can see when you look into a mirror, but does not really exist is called which of the following?

• Real Image
• Fake Image
• Virtual Image
• Digital Image

a real image...

• is produced by virtual rays and can be projected on a screen
• is produced by real rays and cannot be projected on a screen
• is produced by virtual images and cannot be projected on a screen
• is produced by real rays and can be projected on a screen

The fact the two angles are the same is an example of....

• Refraction
• Angle of Incidence
• Law of reflection
• Magnification

Which mirror(s) have a focal point?

• plane only
• concave only
• plane, convex and concave
• concave and convex, but not plane

What is an image called that forms when light rays actually meet

• virtual image
• real image
• diffuse reflection
• regular reflection
