What is an image? Explain its types.
(N/A) An image is an optical representation of an object formed when light rays originating from a point source meet or appear to meet after reflection or refraction.
There are two types of images:
$1$. Real Image: $A$ real image is formed when light rays actually converge at a point after reflection or refraction. It can be obtained on a screen and is always inverted.
$2$. Virtual Image: $A$ virtual image is formed when light rays do not actually meet but appear to diverge from a point when produced backwards. It cannot be obtained on a screen and is always erect.
