What is the refractive index of air if light travels through it at 3.0 108 m/s?

n = c/v = (3.00 x 108 m/s)/(2.76 x 108 m/s) = 1.09. This does not equal any of the indices of refraction listed in the table.

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
