The vitreous humor, a transparent, gelatinous fluid that fills most of the eyeball, has an index of refraction of 1.34. visible light ranges in wavelength from 400 nm (violet) to 700 nm (red), as measured in air. this light travels through the vitreous humor and strikes the rods and cones at the surface of the retina.

A)    λ₁ = 298.5 nm ,  λ₂ = 522.4 nm , B)  f₁ = 7.5 10¹⁴ Hz,  f₂ = 4.29 10¹⁴ Hz ,

C)   v = 2,238 10⁸ m / s

Explanation:

When the light passes through a material medium to another the electrons of the atoms exist, as a formed oscillation, these electors re-emit the radiation with the same frequency, process is resonant, but by the index of refraction we know that the speed of light in the medium has changed, therefore the wavelength must be changed to meet the relationship

In a vacuum        c = λ₀ f

In a material       v = λ f

              n = c / v = λ₀/λ

              λ = λ₀ / n

.a) Let's calculate the new wavelengths in the vitreous humor

With n = 1.34

              λ₁ = 400 / 1.34

              λ₁ = 298.5 nm

              λ₂ = 700 / 1.34

              λ₂ = 522.4 nm

b) as the frequency does not change when changing the medium we can use the values for the vacuum or air

             c = λ₀ f

             f₁ = c /λ₀

             f₁ = 3 10⁸/400 10⁻⁹

             f₁ = 7.5 10¹⁴ Hz

            f₂ = 3 10⁸/700 10⁻⁹

            f₂ = 4.29 10¹⁴ Hz

c) the speed of light in this material medium

            v = λ f

            v = 298.5 10⁻⁹ 7.5 10¹⁴

            v = 2,238 10⁸ m / s

           n = c / v

           v = c / n

           v = 3 10⁸ / 1.34

            v = 2,238 10⁸ m / s
