ratio of speed of light in a vacuum to speed of light in a substance
n
index of refraction
(optical density)
c
speed of light
in a vacuum
v
speed of light in a
medium
inverse - as 'n' increases, speed decreases
no - they have the same index
it will change speed (and therefor refract) a lot
it will not change speed (or refract) much
average frequency of visible light - each frequency has a slightly different index
Low to High - bends toward normal
High to Low - bends away from normal

1 Answer?
Because one part of the incident wave
changes speed before the rest of the wave
Wavelength decreases, speed decreases, frequency
remains the same, period and phase remain the same

the separating of white light into its component colors due to refraction
fastest,
lowest 'n'
bends least
slowest, highest 'n'
bends most
