White light is sent through an interface of a 100% (w/V) glycerol solution (n1 = 1.474) and a 20% (w/v) sucrose solution (n2 = 1.364) at an angle of O1. Incident ray Reflected ray If O1 = 29, determine the angle of O2 in degrees. Refractive index = n, O2 = Refractive index = n, If O1 = 0', determine the angle of O2 in degrees. Refracted ray Of =
