THE REFRACTIVE INDEX OF DENSE FLINT GLASS IS 1.65 AND FOR ALCOHOL 1.36 WITH RSPECT TO AIR. WHAT IS THE REFRACTIVE INDEX OF DENSE LINT GLASS WRT ALCOHOL
R.I. of flint glass w.r.t. air is = aμfg = 1.65
R.I. of alcohol w.r.t. air is = aμal = 1.36
So, R.I. of flint glass w.r.t. alcohol is,
alμfg = (aμfg)/(aμal) = 1.65/1.36 = 1.21
