# 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 the radius of curvature of plane surface?

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.
