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 380 nm (violet) to 750 nm (red), as measured in air. This light travels throughout teh vitreous humor and stikes the rods and comnes at the surface of the retina. What are ranges of
(a) wavelength,
(b) frequency, and
(c) speed of light just as it approaches the retina within the vitreous humor?
