Question

What are the properties of an image formed on a plane mirror?

Answer 1

Hi,

1. The image formed on plane mirror is erect, same size of the object, laterally inverted and virtual i.e they can’t be caught on a screen.

2. Types of curved mirrors: 1) Convex 2) Concave

Convex mirror:

Image is Virtual, upright, and reduced for all positions of object

Concave mirror:

Let

S = Object distance

F = Focal length

S < F : Virtual, upright, magnified

S = F : No formation of image

F < S < 2 F : Real, inverted, magnifiied

3. convex lens

-real or virtual (depending on position of the object)

-enlarged

-inverted if real and erect if virtual

-on the other side of the lens

Concave lens

-virtual

-erect

-diminished

-on the same side as that of the object
