2. SPHERICAL MIRROR
• A spherical mirror can be a concave or a convex mirror depending upon the surface of
the reflection. If it is bulged out then it is a convex spherical mirror whereas if it is bent
inwards it is termed as a concave spherical mirror.
• A typical spherical mirror is a part of a big sphere of which the cut-out has been taken.
• A spherical mirror is a mirror that has the shape of a piece carved out of a sphere.
• A spherical mirror is categorised into two forms, concave and convex.
• Spherical mirrors are the mirrors that are curved in shape and are the part of an
sphere.
• Spherical mirrors are constructed from the glass. One surface of the spherical part is
other part is used for reflection.

3. USE OF SPHERICAL MIRROR
• Spherical mirrors are used by all in day-to-day life.
• It is important that students have a better understanding of the application of spherical
mirrors so that they grasp the concept properly.
• Students often find problems when dealing with the concept because it can prove to be
complicated.
• However, this concept is important because questions from this concept do come in exams.
• This article has a detailed explanation of the application of spherical mirrors.
• Students can find spherical mirror examples which will help them understand the concept.
• The article has explained in detail the examples of concave and convex mirrors and their
definitions, which are important for students to understand. After reading this article students
will be able to write the uses of spherical mirrors and ace their exams.

4. SHPERICAL TYPE
1. Concave mirror:- The definition of a concave mirror says that when a spherical
mirror surface is painted out wards and its inner surface is reflecting, it is called a Concave
A concave mirror is a spherical mirror, which has a reflecting surface, dented inwards.
Concave mirrors reflect and focus incoming light rays (parallel) at a point, called the focus
point. Depending on the distance of an object from the reflecting surface, different types of
images are formed. Concave mirrors are also called converging mirrors since light rays
converge after reflection at concave mirrors.

5. USE OF CONCAVE MIRROR
• Men use them while shaving.
• Dentists use them to see the back of teeth.
• They are used to produce parallel beams of light in torches, vehicle headlights and
searchlights.
• They are used as concentrators in solar cookers and furnaces.
• They are used in reflecting telescopes

6. SHPERICAL TYPE
2. Convex Mirror:- The part of the hollow sphere which is silver painted from the inside and the outer surface is
used for the reflection purpose and is known as a convex mirror. The figure shows a convex mirror.
• A convex mirror is also referred to as a diverging mirror because, when light rays hit its reflecting surface, they diverge.
• Whatever the object's distance from the convex mirror, it always produces a virtual, erect and diminished image.
• Convex mirrors do not focus the light ray toward a point as the rays after hitting always diverge.

7. USES OF CONVEX
MIRRORS
• We have seen these mirrors on the sides of vehicles. Convex side view mirrors show a larger
area in a small space.
• They are placed at curves of roads to give a view of the bend of the road.
• Convex mirrors are also used in reflecting telescopes.
