write the mirror formula and lens formula? explain each terms​

Answer 1

Answer:

Mirror formula is the relationship between object distance (u), image distance (v) and focal length.

Answer 2

* Mirror formula = 1/v + 1/u = 1/f.

The distance between the object and the pole of the mirror is called the object distance(u).

The distance between the image and the pole of the mirror is called Image distance(v).

The distance between the Principal focus and pole of the mirror is called Focal Length(f).

* Lens formula = 1/v - 1/u = 1/f.

The distance between the object and the optical centre is called the object distance (u).

The distance between the image and the optical centre of the lens is called Image distance (v).

The distance between the Principle focus and optical centre of the lens is called Focal length (f).
