Great Mirror Formula Derivation

The derivation of the mirror formula is one of the most common questions asked in various board examinations as well as competitive examinations.

Mirror formula derivation. Reflection and Mirrors The following information is provided to the student. The object distance is the distance of the object from the reflecting surface of the mirror. Thus we use the sign convention during the derivation as well as later while solving problems involving different sets of lenses or mirrors.

Mirror formula is relationship that combines image distanceobject distance and focal length of the mirror. We will use a concave mirror to do it. Mirror Equation Derivation is very common among the students.

Mirror Formula Proof is very easy. From Figure the two right-angled triangles ABF and MPF are similar. Expression for mirror formula is 1u1v1f Here uobject distance as measured from pole of the.

The verification of the mirror formula 1 v 1 u 1 f is shown below. For paraxial rays MP can be considered to be a straight line. In the above figure A B F and M P F are two right-angled similar triangles.

In this video we will derive the mirror formula expression connecting uv and f and magnification formula. How can geometry algebra and simple ray construction be used with a concave mirror in order to develop a relationship between the. Assumptions and Sign conventions To derive the mirror formula following assumptions and sign conventions are made.
