Question

What are spherical mirrors? Describe the convex and concave mirror

Answer 1

A reflecting surface which is a part of sphere is called spherical mirror.
A convex mirror is made by silvering the inner surface of the piece of a hollow sphere such that the reflection takes place from the outer surface
A concave mirror is made by silvering the outer surface of the piece of a hollow sphere such that the reflection takes place.

Answer 2

Spherical Mirrors

A spherical mirror is a mirror which has the shape of a piece cut out of a spherical surface. There are two types of spherical mirrors: concave, and convex. The most commonly occurring examples of concave mirrors are shaving mirrors and makeup mirrors. As is well-known, these types of mirrors magnify objects placed close to them. The most commonly occurring examples of convex mirrors are the passenger-side wing mirrors of cars. These type of mirrors have wider fields of view than equivalent flat mirrors, but objects which appear in them generally look smaller (and, therefore, farther away) than they actually are.

Convex mirror:

a convex mirror is like a normal plane mirror with some exceptions.

Here are some properties of a convex mirror. The first two properties are different from a normal plane mirror.

1) There is a reduced size of the image displayed in the convex mirror compared to the object.

2) Convex mirror covers a larger field of view compared to plane mirror.

3) The images in convex mirror are laterally inverted compared to the object. “Laterally Inverted” refers to the apparent reversal of the mirror’s image from left to right. “lateral” in that context means “sideways” .

4) The image formed in convex mirror is upright and not upside down.

Concave mirror :
A concave mirror is one that has a real focal point (not virtual). How an image in that mirror would be perceived would depend on whether or not the observer is between the mirror the the focal point, at the focal point, or on the opposite side of the focal point from the mirror’s surface. It is also dependent on the vergence of the light falling on the mirror (parallel rays, divergent, or convergent).
