How do we perceive diferent colours?

Answer»

Solution :1.We perceive different colours, because the coical cells in our retina respond to the COLOURES and GIVE INFORMATION about the COLOUR of the OBJECT to the brain.
Brain processes all the information and we see image of the object and the colours.
3. When red colour falls on the eyes, the cells reponding to red light get excited more than those responding to ohter colours and we get the sensation of red colours.
