Question

The refractive index of a medium ' x ' with respect to ' y ' is 2/3 and the refractive index of the medium ' y ' with respect to medium ' z ' is 4/3 . Calculate the refractive index of the medium ' z ' with respect to medium ' x ' .. Find the speed of light in medoum y if speed of light in medium x is 3*10^8 m/s

Answer 1

Answer:

refractive index of medium z with respect to medium x is 9/8

speed of light in medium y is 2 × 10 8 m/s

Answer 2

Explanation:

x in respect to y=speed of light in air\speed in y=

2/3=3*10^8/speed in y

speed in y=3*10^8*3/2

4.5*10^8
