Answer: Answer:Since it's vacuum, refractive index is taken to be 1. use snell's law of refraction n1xsin(i)=n2xsin(r) n1=1 sin(i)=sin(2r) n2=1.5 sin(r)=sin(r) ... has maximum angle of refraction when travelling from glass to air for same angle of incidence? .If a ray of light travelling through the air strikes a glass slab at an angle of 30°.
