Question

If the speed of light in glass is 2 * 108 m/s, and that in air is 3 * 108 m/s, calculate the refractive
index of glass with respect to air.
rind the refractive indey of the​

Answer 1

Answer:

even I left these questions

Answer 2

Relative refractive Index= speed of light in med_1/ speed of light in med_2

so, refractive index= 3×10⁸/2×10⁸

= 3/2=1.5

answer should be 1.5
