Question

If the speed of light in
a glass is 2×10 ka power6 m/s and
that in air is 3 x 10 ka power 6 m/s.
Calculate the refraction index
of a glass with respect to air.

Please answer fast .......​

Answer 1

Ref. index of g = c / vg

ref. index of g = 2×10^6 / 3 × 10^6

ref. index of glass = 2/3

ref. index of glass = 0.6

Answer: 0.6
