Question

how can we find velocity of light in glass and water if their refractive indexes are given . please explain the topic in breif with suitable examples

Answer 1

v= c/v1
where v = velocity of light
c = speed of light
v1 = refractive index
In this formula we found the velocity of light when refactive index is given

For example refactive index is 2 then velocity of light is
v= c/v1
speed of light is 3×10^8
v= 3 ×10^8 / 2
v = 1.5 ×10^8

i hope this help u
