# What is the radius of curvature of plane mirror Class 10?

## What is the radius of curvature of plane mirror Class 10?

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.

## Why is radius of curvature of plane mirror infinity?

The radius of curvature of a plane mirror is infinity. A plane mirror is a part of a sphere of infinite radius because in the limit the “curved” surface of the sphere becomes straight. So the radius of curvature is infinity.

## What is the focal length and radius of curvature for a plane mirror?

The focal length of a plane mirror is infinity as the image can be formed at an infinite distance inside the mirror. A plane mirror can be recognised as a spherical mirror of infinite radius of curvature. Focal length is half of the radius of curvature and hence it is infinity.

## What is the formula of radius of curvature of mirror?

The focal length of a spherical concave mirror is given as f=R2, where R is the radius of curvature of the mirror. It is given that R=24cm.

## What is the radius of curvature of lens?

Definition: Radius of curvature of lens is the radius of the hollow sphere of glass of which the lens is a part. Each lens has two radii of curvature. From this formula we can say that focal length of lens is inversely proportional to refractive index of material of lens medium.

## What is the radius of curvature of a 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 is radius of curvature of the lens?

Definition: Radius of curvature of lens is the radius of the hollow sphere of glass of which the lens is a part. Each lens has two radii of curvature. Focal length,Reractive index and radius of curvature are related by lens makers.-

## What is the formula of spherical mirror?

Suppose an object is placed u cm in front of a spherical mirror of focal length f such that the image is formed v cm from the mirror, then u, v and f are related by the equation; 1/f= 1/u + 1/v. This equation is referred to as the mirror formula. The formula holds for both concave and convex mirrors.

## When radius of curvature of a mirror is 20 cm the focal length is 10 cm True False?

So, focal length = 21× radius of curvature = 21×20 cm = 10 cm.

## Is the radius of curvature of a plane mirror infinite?

A plane mirror may be considered to be a part of an infinitely large spherical surface. And, an infinitely large spherical surface will have infinite radius. So, radius of curvature for a plane mirror will be infinite. Was this answer helpful?

## How tall is a plane mirror in feet?

Radius of Curvature Plane Mirror A plane mirror is a spherical mirror with an infinite radius of curvature. O Height = I Height 10/25/11 3 Spherical Mirrors

## Is the radius of curvature of a plane equal to zero?

O The radius of curvature of a plane mirror is equal to zero. In terms of the mirror equation, if di -do, then must go to infinity, which means r 2f O The radius of curvature of a plane mirror is equal to infinity. In terms of the mirror equation, if dr -do, then must go to zero, which means O The radius of curvature…

## When does a mirror fit in a sphere?

If we increase the radius of a sphere we see that its circumference starts to straighten out. Therefore only when the radius of curvature ( ie radius of sphere of which the mirror is a part) is of infinite length will the mirror fit in the sphere. 27/03/2021
