Question

speed of light in air is 3 x 10 power 8 m s -1 and the refractive index of a medium is 1.5.find the speed of light in the medium.​

Answer 1

Hope it helps u☺☺☺☺☺

Answer 2

Step-by-step explanation:

speed of light in air is 3×10power8ms-1 where the refractive index of air =1 and it medium index =1.5 then 3×10power 8 ÷ 1.5 =2×10 power8
