What Is The Radius Of Curvature Of A Mirror? - Fixanswer

R=CF+FP

. In other words, in the small-angle approximation, the focal length f of a concave spherical mirror is half of its radius of curvature, R: f=R2.

What is a curvature of a mirror?

It can also be defined as

the spherical distance between the point at which all the rays falling on a lens or mirror either seems to converge to

(in the case of convex lenses and concave mirrors) or diverge from (in the case of concave lenses or convex mirrors) and the lens/mirror itself.

What is the formula for curved mirrors?

1/f= 1/u + 1/v

. This equation is referred to as the mirror formula. The formula holds for both concave and convex mirrors.

What is radius of curvature in science?

The radius of curvature of a spherical mirror is

the radius of the circle of which the spherical mirror is a part

. It can also be defined as the distance between the centre of curvature of the mirror and the pole of the mirror on the principal axis. The radius of curvature is also a measure of how curved the mirror is.

Can radius of curvature negative?

The distance from the vertex to the center of curvature is the radius of curvature of the surface. The sign convention for the optical radius of curvature is as follows: …

If the vertex lies to the right of the center of curvature, the radius of curvature is negative

.

What is the radius of curvature of a plane mirror answer?

The plane mirror is a part of sphere with

infinite radius

. It’s every part is a part of sphere. Hence, its radius of curvature is infinite.

What is the radius of curvature of a plane mirror explain?

The radius of curvature of a plane mirror is

infinity

. A plane mirror may be considered to be a part of an infinitely large spherical surface. Radius of curvature of mirror is defined by the radius of the sphere from which the mirror was cut from.

What is the radius of curvature of plane surface?

The radius of curvature of a plane surface is

infinity

.

The radius of curvature of a plane mirror is infinity. It can be considered that the plane mirror is a part of infinitely large spherical surface. For a infinitely large spherical surface, the radius of curvature is infinite.

What are the two types of curved mirrors?

Curved mirrors have a variety of forms, two most common types are

convex and concave

. A convex mirror has a surface that bows outwards and a concave mirror has a surface that caves inwards. Each has distinctive characteristics in terms of size of image and whether the image is real or virtual.

What is called the Centre of curvature of a mirror?

(c) Pole: The centre of a spherical mirror is called

its pole

. (d) Principal axis: The straight line passing through the centre of curvature and pole of a spherical mirror is called its principal axis.

Is Centre of curvature part of a mirror?

Center of curvature

is not part of the mirror

, rather it lies outside the mirror. Concave mirror and convex mirror can be formed from a single spherical glass by slicing it but polishing both the slices in the opposite manner.

What is mirror formula?

A mirror formula can be defined as the formula which

gives the relationship between the distance of object ‘u’, the distance of image ‘v’, and the focal length of the mirror ‘f’

. The mirror formula is applicable for both, plane mirrors and spherical mirrors (convex and concave mirrors).

What is the formula to calculate mirror?

u is the Object distance.
v is the Image distance.
f is the Focal Length given by f=R2. f = R 2.
R is the radius of curvature of the spherical mirror.

What is formula of convex lens?

1. What is the Lens Formula for Convex Lens? Ans. According to the convex lens equation,

1/f = 1/v + 1/u

. It relates the focal length of a lens with the distance of an object placed in front of it and the image formed of that object.
