Question

to find the value of v for different values of u in case of concave mirror and find its focal length in hindii

Answer 1

1/v=1/f+1/u
iss formula ka use kar leo

Answer 2

1/f = 1/v + 1/u

or, f = uv/(u+v)

ihan pe f mirror ka focal length hay, v distance hay object aur mirror ke bich me, u distance hay mirror aur image ke bich me.

Agar 2 values pata hoga f, v aur u ke andar, tab remaining ka value easily pata laga ja sakta hay upar ke formula use karke.
