j) The index of refraction for a material generally decreases with increasing wavelength. T / F
k) The refractive index of air is 1m/sec. T / F

n) Index of refraction can be found with the ratio of speed of light in medium to speed of light in vacuum. T / F
o) The large index of refraction corresponds to a relatively slow light speed in that medium. T / F
Definition Definition Rate at which light travels, measured in a vacuum. The speed of light is a universal physical constant used in many areas of physics, most commonly denoted by the letter c . The value of the speed of light c = 299,792,458 m/s, but for most of the calculations, the value of the speed of light is approximated as c = 3 x 10 8 m/s.
