CBSE-Light
CBSE-Light We can see colours because The retina of our eyes has a large number of light sensitive cells. The cells on the retina are of two shapes: (i) Rod shaped and (ii) Cone shaped The rod shaped cells of our retina respond to the intensity of light. The cone shaped cells of our retina respond to colours. These cells make us see colours and to distinguish between them. Thus cones make colour perception possible.
