The word ""virtual"" refers to something that exists in effect but not in actual fact. How does this definition relate to the virtual image you see of yourself in a plane mirror?

Explanation:

In mirror generally, the type of image that can be formed by an object placed in front of it can either be a real image or a virtual image. Virtual images are images that are formed behind the mirror.

Virtual images are also images that cannot be formed from a photographic screen i.e the image formed by an object in front of the mirror cannot be reproduced compare to a real image than can be formed on a screen. This is the reason why we are able to get a picture of our self when pictures are taken using a photograph (For real images). This is not the same for virtual images.

We can only see ourselves when we stand in front of a mirror but in actual fact, we cannot reproduce the image of us we are seeing in the mirror.
