Constants SOLUTION Light rays that enter your eye are affected by the fluid that fills the eyeball, called the vitreous humor (Figure 1). When red light from a l = 633 nm helium-neon laser enters your eye, its wavelength drops to 474 nm. Use this information to calculate the index of refraction of the vitreous humor and the speed and frequency of light passing through it. SET UP AND SOLVE We don't need to sketch this problem because we're interested...
