Real, erect and has the same height as the object

Answer 1

(a) One of the Plane mirror characteristics is that

The image distance from the mirror is equal to object distance from the mirror.

This implies the image distance from the mirror = 1.6m

It's given person distance is 1.6 m from plane mirror.

Distance between person and his image is 1.6+1.6= 3.2m

(b) characteristics of plane mirror

Virtual, erect and has the same height as the object

-Virtual images are images that are formed in locations where light does not actually reach. Light does not actually pass through the location on the other side of the mirror; it only appears to an observer as though the light is coming from this location

- An erect image, in optics, is one that appears right-side up.

- plane mirrors create image of same height as that of object.
