Question

find the mirror formula for plane mirror​

Answer 1

Answer:

is this what you want

Answer 2

I/f = 1/v - 1/u

As we know that, Nature of the image of plane mirror is virtual and errect and also alif the same size object. So, clearly we conclude that, v = u

Substituting this in above equation,

1/f = 1/v - 1/v

1/f = 0

f = 1/0 = ∞

• Focal length of plane mirror is infinity.
