Question

A ray light enter the glass. refractive index of glass with respect to water is 1.12? find the absolute refractive index of water if absolute refractive index of glass is 1.5

Answer 1

refractive index of glass w.r.t water   ng/nw =1.22
refractive index of glass wrt to vacuum  =1.5
 the absolute refarctive index of water is calculated by the formula
ng/nw= ng/na *na/nw
1.12=1.5* na/nw
na/nw=1.12/1.5
nw/na =1.5/1.12
=1.33

Answer 2

Hope this will help you alot ....
