briefly explain the various parts of the eye that are required to get the lightwaves through the sensation process (explain the job of the parts of the eye in the order the lightwave will travel). b) Lightwaves differ in length, height, and width - which explain different colors that we see. If I am looking at a dull, maroon sign, describe the likely length, height, and width of the waves.
Hwhen light enters human eye, it passes through cornea, then through the iris it enters the eye and then passes through the lens of the eye and then the fluids inside the eye finally top reach the retina
the retina has these chemical molecules that change shape when irradiated by light photons and these molecules help in sending the sensation of vision to the brain through the optic fibre
b. for dull maroon sign the light reflected from it has longer wavlength and less amplitude ( as it is dull and has less light reflecting from it)
the wavelength of the waves will be about 600 nm that is closer to the wavelenght of red color
