Plane Mirrors and Concave Mirrors
In this type of mirror, the image is upright and the same size as the actual object.
What is Plane Mirror?
Concave lenses are __________ in the middle.
What is thinner?
Convex lenses are ____________ in the middle.
What is thicker?
What do we call it when light changes direction (bends) as it enters a transparent medium.
What is refraction?
This is the name for an image that appears on the other side of the mirror.
What is a virtual image?
Concave lenses refract incoming light in this direction.
What is outward or diverging?
Convex lenses refract incoming light in this direction.
What is inward or converging?
The angle of incidence is equal to the angle of refraction. True or False?
What is false?
This type of mirror is used in flashlights and lighthouses.
What is a concave mirror?
Concave lenses form this type of image.
What is a virtual?
When an object is behind the focal point of a convex lens, this type of image is formed.
What is real?

A) Less dense
B) Denser
C) Normal
What is B) Denser?

A) behind the focal point
B) on the focal point
C) in front of the focal point
What is B) on the focal point?
An image formed by a concave lens is always ________.
A) closer
B) farther
C) inverted
What is A) closer?
Where does an object need to be in order to form an upright, virtual image on a convex lens?
A) behind the focal point
B) on the focal point
C) in front of the focal point
What is C) in front of the focal point?

A) the same distance
B) farther
C) closer
What is c) closer?
