spherical mirror is a mirror and lens is a lens
spherical mirror is made of broken glass .sperical lense is used to see the font in big size
The type of spherical mirror whose reflecting surface is bulged outwards, in the sense that its face is opposite to the centre of the sphere is known as a convex mirror. A curved mirror whose reflecting surface is bent inwards, i.e. it faces towards the centre of the sphere is called a concave mirror.
there are two types of spherical mirror.. concave and convex
a curved mirror is the mirror a curved reflecting surface the surface may be either concave or convex
thank u hope it will help you mark it as brain list
Spherical mirror the surface of mirror is curve .
both concave and convex mirror are spherical.
Plane mirror it produce virtual,straight and of same size image
Hope it helps you.
Spherical Mirror => It is curved mirror which is the part of a hollow spherical glass.
There are 2 types of spherical mirrors :-
(1) Concave mirror
(2) Convex mirror
Plane Mirror => It is a flat mirror which is not curved.
Properties of plane mirror:-
(1) They form real and inverted images
(2) They form laterally inverted
(3) The distance between object and mirror is equal to the distance between image and mirror.
HOPE IT HELPS
hope you solve it yourself..
it's a ncert book question
moi of disc is (mr^2)/2 so for moi to be equal mass of disc should two times of mass of ring.
