how to find focal legth of conclave mirror

Answers

Answered by jackson97

In order to find the focal length of a convex and concave mirror, we have to use this formula:
1/v+1/u=1/f

yrd: your formula is wrong.

jackson97: give a reason.

yrd: you have used lens formula but the question is regarding mirror formula

jackson97: then prove that your formula is right

yrd: take a deep breadth open your ncert book and check what is mirror formula and what is lens formula

yrd: thank me later

yrd: when the question is about mirror how can u insert lens formula?

jackson97: i m not an Cbse student bro

yrd: then google it

Answered by yrd

we can find the focal length of a concave or convex mirror by using mirror formula
i.e. 1/f = 1/v + 1/u
where f= focal length
v= image distance
u = object distance

note:
1) in concave mirror
f = always negative
u = always negative

yrd: matk brainliast if it helps
