## What is the formula of mirror in physics?

Let’s explore the mirror formula (1/f = 1/v+1/u) and see how to locate images without drawing any ray diagrams.

## What is mirror formula answer?

Mirror formula is the relation between the focal length f of the mirror, the distance u of the object from the pole of the mirror, and the distance v of the image from the pole. 1/v +1/u = 1/f.

What is mirror formula derivation?

Derive the relation u1+v1=R2 for a concave mirror. Solution: The relationship between object distance (u), the image distance (v) and the focal length (f) of the mirror is known as the mirror formula.

What is mirror and lens formula?

A mirror can be plane or spherical (concave or convex) A lens is usually curved from either one or both surfaces. Mirror formula is 1/f = 1/v + 1/u. Lena formula is 1/f = 1/v – 1/u.

### What is mirror equation explain with diagram?

It is an equation relating object distance and image distance with focal length is known as a mirror equation. It is also known as a mirror formula. In a spherical mirror: The distance between the object and the pole of the mirror is called the object distance(u).

### What is mirror formula and lens formula?

What is mirror physics?

A mirror is defined as reflecting surface and can be explained by the law of reflection, which states that when a ray of light is made to fall on the reflecting surface, the reflected ray has its angle of reflection, incident ray, and the reflected ray are normal to the surface at a point of incidence.

What is the lens equation?

The lens equation allows us to understand geometric optic in a quantitative way where 1/d0 + 1/di = 1/f. The lens equation essentially states that the magnification of the object = – distance of the image over distance of the object.

## Is mirror equation and lens formula same?

A lens is a transparent medium, so distances can be measured in one direction. But a mirror is a reflecting surface so the rays return towards the origin, so the rays suffer a reversal of direction. So the sign difference is necessary in a mirror formula as against a lens formula.

## What is mirror equation class 10?

f = R/2 ∴ The mirror formula can be written as 1/u + 1/v = 1/f = 2/R This formula is valid in all situations for all spherical mirrors for all positions of object. Numerical – Question. An object is placed at 25 cm in front of a concave mirror of focal length 15cm.

What is reflection law?

Definition of law of reflection : a statement in optics: when light falls upon a plane surface it is so reflected that the angle of reflection is equal to the angle of incidence and that the incident ray, reflected ray, and normal ray all lie in the plane of incidence.

What is the principle of mirror?

The mirror principle surmises that a complex word is generated in a derivation where the root of a given word merges lower than all subsequent suffixes that attach to that word.
