SUMMARY
The discussion revolves around calculating the angle of a refracted ray when a ray of light strikes glass with a refractive index (n) of 1.5 at an angle of 30 degrees. Using Snell's Law, which states that n1*sin(theta1)=n2*sin(theta2), the assumption is made that the incident medium is air, where n1 is 1. This leads to the conclusion that the angle of refraction can be determined by substituting the known values into the equation.
