Question

Write The Mirror Formula, Lens Formula And Formula Of Power Of Lens.

Answer 1

Mirror formula:

1/v + 1/u = 1/f

Lens formula:

1/v - 1/u = 1/f

Formula of Power of Lens:

P=1/f

Here,

v=Image distance

u=Object distance

f=Focal length

P=Power of Lens

Answer 2

Mirror formula:

1/v + 1/u = 1/f

Lens formula:

1/v - 1/u = 1/f

Formula of Power of Lens:

P=1/f

Here,

v=Image distance

u=Object distance

f=Focal length

P=Power of Lens
