Question

mirror formula for plane mirrors​

Answer 1

Answer:

1/v+1/u=1/f........

Answer 2

Answer:1/f =1/v+1/u

While v= -u.

Explanation:

This is the formula derived practicing the experiment of plane mirrors.

Here the mirror we have is plane mirror this the image distance is equal to the object distance with a minus sign. Thus we get the equation from the derivation and repeatedly finding the image and object distances.

And thus we get an equation which applies to all the plane mirrored images. And that is-

1/f = 1/v+ 1/u

Hope this helps
