Question

State Snell's law of refraction. The refractive index of glass is 1.5 . And find out the speed of light in glass.

Answer 1

Answer:

v=2×10^8

Explanation:

velocity in glass is 2×10^8m/s

Answer 2

Snell's law of refraction states that :

sin i = n (constant)

sin r

speed of light in glass = c/n

= 3 x 100000000/1.5

= 200000000 m/s .
