Question

Absolute refractive index of a medium is 1.5 while that of medium q is 2.2 in which of these media light propagates in the lower speed give reason to support your answerabsolute refractive index of a medium is 1.5 while that of medium q is 2.2 in which of these media light propagates in the lower speed give reason to support your answer

Answer 1

Explanation:

absolute refractive index means refractive index of any medium with respect to air / vaccum .

if refractive index of medium is 2.2 then ,

speed of light in vaccum / speed of light in medium= 2.2 ,we know the speed of light in vaccum is 3×10ki power 8 .

we get 3×10ki power 8 / speed of light in medium =2.2

=1.25 × 10 ki power 8
