Answer:
The image behind the mirror is called a virtual image because it cannot be projected onto a screen—the rays only appear to originate from a common point behind the mirror. If you walk behind the mirror, you cannot see the image, because the rays do not go there
Answer:
Lateral Shift When a ray of light is incident on a glass slab, the emergent ray coming out of the slab will be parallel to the incident ray. The perpendicular distance between the direction of incident ray and emergent ray is called the lateral Shift. It is denoted by d.

The average velocity is obtained by ( u + v)/2.
<h3>What is average velocity?</h3>
The term velocity refers to the rate of change of displacement with time. Velocity is a vector quantity thus it has both magnitude and direction. The velocity of a body could also be shown by the use of the vector notation.
To obtain the average velocity;
Let the initial velocity be u
Let the final velocity be v
It then follows that the average velocity = ( u + v)/2
