How does physics relate to colour vision and colour blindness???

What is colour vision and colour blindness and how do they relate to physics through sight and light????

Well, for starters, physics explains how the physical characteristics of the eye work to focus light on the retina. The lens and the way that it bends light are described by physics.

The way that the eye absorbs light is also physics, and the different properties of different wavelengths of light are what allow specific parts of the eye to distinguish different colors. A lack of one part of the eye that distinguishes, for example, red, means that the person cannot tell red from other colors. What other color lights up depends on what receptor is closest to red. In this case, the green receptors are able to pick up on red light, so red and green show up as the same color to someone who has this form of color blindness.

The actual physics involved can get very complicated, depending on how deep into physics you are. I’ve included a couple of links that describe some of the physics involved in sight.
