Answer:
refractive index is defined as the ratio of speed of light in vaccum to the speed of light in mediun
n= speed of light in vaccum/spped of light in medium
Explanation:
we have refractive index (n) = speed of light in vaccum/speed of light in medium.
it can be expressed as n=c/v
2.42= 3×10power 8/speed of light in medium
v = 1.23×10power 8 metre/sec
