1. The problem statement, all variables and given/known data
A ray of light is incident in water on a plane waterglass boundary. The angle of incidence is 30 degrees. Calculate the angle of refraction. (Refractive index of glass with respect to air =3/2, refractive index of water with respect to air = 4/3). 2. Relevant equations n1sini = n2sinr 3. The attempt at a solution I tried approaching it with several methods, but I am puzzled. How do you get the glass to water refractive index from the data given?? Any help would be greatly appreciated. Thank you!

Think of the definition of the refractive index.

It is not necessary to solve this problem. You can use the relevant equation n1sini = n2sinr to find r. Here n1 is the refractive index of water. and n2 is that of glass.
