What is difference between Real image and virtual image?

Answer 1

Real image-

1. They are formed by actual intersection of light rays.
2. It is inverted.
3. It can be projected on a screen.
4. It is formed on the mirror.

Virtual image-

1. It is formed when rays appear to meet at a point.
2. It is laterally inverted and erect.
3. It cannot be projected on a screen.
4. It is formed behind the mirror.

Answer 2

A real image is formed when light rays actually converge at a point, such as on a screen. A virtual image is formed when light rays appear to converge at a point but do not actually do so, such as in a mirror.

Answer 3

Real ground is when a terminal is connected physically to the ground or earthed. where as virtual ground is a concept used in OpAmps in which a node a assumed to have the potential that of the ground terminal.

Answer 4

There is no such thing as "virtual current" to my knowledge. There is reactive current, which is generally a result of loads being inductive or capacitive.

Answer 5

A Real image can be projected on a screen while a virtual image cannot. A Real image is inverted but a virtual image is upright.
