Question

class 10th Light and Reflection all formulas​

Answer 1

Mirror formula

$\frac{1}{f} = \frac{1}{v} + \frac{1}{u} \\ m = - \frac{v}{u}$

lens formula

$\frac{1}{f} = \frac{1}{v} - \frac{1}{u} \\ m = \frac{v}{u}$

Answer 2

Mirror Formula -

$\frac{1}{v} + \frac{1}{u} = \frac{1}{f}$

where;

v = image distance

u = object distance (which is always negative)

f = focal length of the mirror

$m \: = \frac{ - v}{u} = \frac{h2}{h1}$

where;

m = magnification

h2 = size/height of image

h1 = size/height of object

R = 2f

where;

R = radius of curvature

Lens Formula -

$\frac{1}{v} - \frac{1}{u} = \frac{1}{f}$

$m \: = \frac{v}{u} = \frac{h2}{h1}$

P = 1/f

where;
P = power in Diopters (D)
and 'f' should be in meters
