Question

What is a concave mirror, and convex mirror,concave lens,convex lens.

Answer 1

concave mirror:if the convex surface is silvered then the concave surface acts as reflecting surface is called concave mirror

convex mirror:if the concave is silvered then the convex surface acts as reflecting surface is called convex mirror

Answer 2

Heya!

Here is your answer.

There are mainly two types of spherical mirrors:

•Concave mirror

•Convex mirror

Concave mirror

•A concave mirror usually forms a real, inverted and magnified image.It can also form a virtual image depending upon the position of the object placed. Example ->A magnified glass.

Convex mirror

•A convex mirror forms a virtual, and deminished image.It cannot form a real inverted image. Example -> A shaving mirror.

Now,let me categorise the lenses.

There are two types types of lenses:

•Concave lens

•Convex lens

These two types of lenses,together form the biofocal lenses.

Concave lens

•A concave lens usually forms a virtual,erect and deminished image.

Convex lens

•A convex lens forms a real,inverted and magnified image. It cannot form a real inverted image.
