Question

Prove that the speed of light is 3 * 10^8 m/s or 3 lakh km/s ​

Answer 1

Speed of light in air is 3*10^8 m/s and speed of light in common glass is 2*10^8 m/s.Calculate the refractive index of glass.

Answer:

Glass refractive index is defined as the ratio between the speed of light in the vacuum and the speed of light in the glass.

Refractive index of glass (ng) = Speed of light in vacuum/speed of light in the glass.

ng = (3 ×108)/ (2 ×108)

ng = 1.5

By this formula u can solve
