In optics we mainly discuss the five types. The five are 1)plane mirror 2)concave mirror 3)convex mirror and concave and convex lens for a plane mirror as it is a part of a plane but not of a curved one so radius of curvature is zero and concave mirror is a part of a sphere the radius of curvature will be the radius of the sphere
Find the normal acceleration a.
R = v^2/a where v is the tangential velocity.
Be specific dude. Mention whether for a lens or for a mirror?
There are many conditions, likena medium is present on the other side of lens and like that,.
Twice of focal length is called radius of curvature
U can find it by many ways...
It is double of focal length
U can use formula:-
U is object distance
V is image distance
R is radius of curvature
This formula u can apply to concave as well as convex mirrors.....
Just thing is about sign convention...
This is a very important topic for jee advance aspirants to known about radius of curvature. @Kunal- it varies from conic to conic. For example it is different for parabola to that if circle
The radius of the sphere of which the mirror is a part of dat sphere this is known as radius of curvature
