Question

is mirror formula applicable to plane mirror??

Answer 1

yes . it is applicable to plane mirror where incident ray , normal and reflected ray , together lies on same side and same plane . where angle of incidence is always equal to angle of reflection .

Answer 2

Yes, it is true. The mirror formula applicable to the plane mirror.

The mirror formula is 1/f = 1/v+ 1/u

Generally, we know that the plane mirror v= -u so 1/f = -1/u + 1/u = 0

Hence the f value is 0 that means infinity.

U = object distance

V = image distance

F= focal length

The mirror formula applicable to all types of mirrors.

Mirror formula states that the relationship integrates image distance, object distance and focal length of the mirror.
