Curved Mirrors

What type of image is produced by an object that is far from a concave spherical mirror?

• smaller and upside down

• larger and upright

• smaller and upright

• larger and upside down

What distinguishes a real image from a virtual image?

• Real images are inverted, whereas virtual images are upright.

• Real images can be displayed on a surface, whereas virtual images cannot.

• Real images can be larger or smaller than the object, whereas virtual images are equal in size to the object.

• Real images are possible with any type of mirror, whereas virtual images only occur with flat mirrors.
