Question

If the refractive index of first medium with respect
to second medium is 1.6, then the refractive index of
second medium with respects to the first medium is _______​

Answer 1

Answer:

Explanation:

Refractive index = speedoflightinvacuumspeedoflightinmedium

Since the refractive index of diamond is more, hence the speed of light is lesser in diamond.  

Let speed of light in water vevw and in diamond bevd.  

Refractive index of diamond w.r.t water is say n = speedoflightinwaterspeedoflightindiamond

n=VwVd

Dividing both numerator and denominator by speed of light [c] we get  

n = (Vwc) ÷ (Vdc) = Inverse Ratio of refractive index of water and diamond.  

n=2.421.33 = 1.82 (approx.)
