Question

Give mirror and magnification formula and in sign convention and its conclusions...

Answer 1

hloo dear ....

formula of magnification and mirror formula is

1/v + 1/u= 1/f is mirror formula

m= h'/h magnifivation

the coclusions are

if v is negative then image is on left

if v is positive then image on right

if m is negative then image formed is real and inverted

i m is is positive the image formed is vitual and errect

Answer 2

hloo dear....

Mirror formula..:- 1/v + 1/u= 1/f

Magnification:- m= h'/h = -v/u

The conclusions of sign convention are..

if V is -ve the image is on left side

If V is +ve then image on right side

if M is +ve then image is virtual and effect

If M is -ve the image is real and inverted
