Taking the speed of light in vacuum to be 3.000 x 10^8 m/s, find the speed of light in: a. air b. diamond c. crown glass d. water data: nair =1.0003; ndiamond = 2.420; nwater = 1.340 ncrown glass = 1.500

Explanation:

The speed of light in vacuum is, c = 3 × 10⁸ m/s

We have to find the speed of light :

(a) In air :

The equation of refractive index is given as :

(b) In diamond :

The equation of refractive index is given as :

(c) In crown glass :

The equation of refractive index is given as :

(4) In water :

The equation of refractive index is given as :

Hence, this is the required solution.

gravity

explanation:

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.
