Question

Write differences between (a) real and
virtual image (b) Convex & Concave mirror
​

Answer 1

Difference Between Real Image and Virtual Image

Real Image Virtual Image

Real images are inverted Virtual images are erect

Convex lenses form a real image Concave lenses form a virtual image

Real images are formed on the screen Virtual images appear to be on the lens or the mirror itself

Real images are formed by a concave mirror Plane, convex mirror and concave lens form a virtual image

Real images are formed due to the actual intersection of light rays Virtual images are formed due to the imaginary intersection of light rays

Therefore, we can say that the difference between real and virtual images is that the real image can be obtained on the screen whereas the virtual image cannot be obtained on the screen.

Concave mirror Convex mirror

It is also called a converging mirror.

It is also called a diverging mirror.

It has a real focus.

It has a virtual focus.

The magnification of a concave mirror can

be greater, equal or less than 1.

The magnification of convex mirror is always less than 1.
