(1) When the image is real (2)When the image is virtual.​

Answer 1

hey mate!!

here is ur answer

1.MIRROR FORMULA

>>

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

>>

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

if image is real magnification is negative

if image is virtual magnification is positive

hope the answer helps u
