A ray of light enters a rectangular glass block and is incident on the lower face of the block. Angle of incidence is `30^(@)`. Part of the ray is reflected inside it and the rest emerges out of the block. Refractive index of glass is 1.5. What is the angle between the emergent ray and the reflected ray? `[sin 48^(@) = 0.75]`
