Derivation of Mirror Formula. Mirror Formula: The mirror formula is used to give the relation between the focal length of the mirror, the object O and the image V. Derivation of formula for convex mirror: Let AB be an object placed on the principal axis of a convex mirror of focal length f. u is the distance between the object and the mirror and v is the distance between the image and the I get the derivation of a mirror formula for a point. please derive the mirror formula for concave and convex mirrors explain it broadly pleas 6ar7ocuu -Physics -

I do not want to make confusion in your mind and write down the equations that I get from similarity of two triangles. I won't try this proof.

Positions in the space around a spherical mirror are described using the principal axis like the axis of a coordinate system. The pole serves as the origin.

## How do you derive the mirror equation with a convex mirror? | Physics Forums

Locations in front of a spherical mirror or a plane mirror, for that matter are assigned positive coordinate values. The distance from the pole to the center of curvature is called no surprise, I hope the radius of curvature r.

The distance derivation of mirror formula the pole to the focal point is called the focal length f. The focal length of a spherical mirror is then approximately half its radius of curvature.

We will assume it to be exactly true until becomes a problem. For many mundane applications, it's close enough to the truth that we won't care. Derivation of mirror formula not until we encounter situations requiring extreme precision that we'll deal with this aberration as it is literally called.

## - Derivation of Mirror Formula

The mirror formula is written as: Assumptions for Derivation Of Mirror Formula The following derivation of mirror formula are taken in order to derive the mirror formula. The distances are being measured from the pole of the mirror.

According to the convention, the negative sign indicates the distance measured in the direction opposite to the incident ray while the positive sign indicates the distance measured in derivation of mirror formula direction of the incident ray. In fact the first formule would be derived by integrating, as follows: Your using the distributive property Question: Imagine a ball hanging from the ceiling on a string that is then set swinging in a horizontal circle.
