Question

The refractive index Of alcohol and turpentine oil with respect to air are 1.36 and 1.47 respectively.FIND THE REFRACTIVE INDEX OF TURPENTINE OIL WITH RESPECT TO ALCOHOL .wHICH ONE OF THESE WILL PERMIT THE LIGHT TO TRAVEL FASTER

Open in App

Solution

Refractive index of oil w.r.t. alcohol =1.47/ 1.36 = 1.08
velocity of light in media is inversely proportional to refractive index of the medium.
hence velocity of light in alcohol is more than that of oil.
