Heya mate ...
==========
It is given that Refractive index of helium , μ = 1.55
We know,
If c is the speed of light and visited is the speed of light in medium, then the refracive index of the medium,μ is given by :-
μ = Speed of light in air / Speed of light in medium
= c / v
A/Q,
1.55 = c / v
It means if the Refractive index of the helium is 1.55 , then the ratio of speed of light in air with respect to speed of light in helium is 1.55
Hope it helps !!
