Question

Which of the following choices describes the type of image formed by a plane mirror?

Answer 1

virtual upright and the same size

Answer 2

Virtual, Upright and the same size

Step-by-step explanation:

As we know for plane mirror we have

`d_i = -d_0`

image distance is same as that of object distance but on opposite side of the mirror.

now for the magnification we have

`m = -(d_i)/(d_0)`

`m = +1`

since magnification is positive so it must be virtual and upright image and since the magnitude of magnification is exactly 1 so it must be of same size as that of object size
