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

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.
