You stand at a position that is 1.55 m in front of a plane mirror. The image that is created will be:

A. Real and 1.55 m away from you
B. Virtual and 3.1 m away from you
C. Real and 3.1 m away from you
D. Virtual and 1.55 m away from you

Answer :

The image that is created will be b) Virtual and 3.1 m away from you.

Plane mirrors always produce virtual images, which means the image cannot be projected onto a screen. In a plane mirror, the image appears to be the same distance behind the mirror as the object is in front of it.

Given the positions:

  • You are 1.55 meters in front of the mirror.
  • The virtual image will appear 1.55 meters behind the mirror, making it seem like it is 3.1 meters away from you when including the distance you are from the mirror plus the distance the image appears behind the mirror.
