The speed of light in a vacuum is approximately 2.99 × 108 m/s, and the speed of light through a piece of glass is approximately 1.97 × 108 m/s. what is the index of refraction for the piece of glass? a) 0.66 b) 1.52 c) 1.02 × 10^8 d) 4.96 × 10^8

Option (b) is correct.The index of refraction for the glass is 1.52

Explanation:

velocity of light in vacuum= C= 2.99 x 10⁸m/s

Velocity of light in glass = V= 1.97 x 10⁸m/s

The refractive index is given by n=

n= 2.99 x 10⁸/1.97 x 10⁸m/s

n= 1.52

Thus the refractive index of glass is 1.52

The index of refraction for the piece of glass is 1.52

Explanation:

Given that,

Speed of light in vacuum,

Speed of light through a piece of glass is,

The ratio of speed of light in vacuum to the speed of light in a medium is called refractive index i.e.

n = 1.52

Hence, the index of refraction for the piece of glass is 1.52

answer: good job it's all correct !

explanation:

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
