If a ray of light propagating in air strikes a glass slab at an angle

1.	If a ray of light propagating in air strikes a glass slab at an angle 60° with the surface of the slab, the angle of refraction is _____________A)more Than 30°B)less than 30°C)60°D) 30°
Answer» (a) because the incident RAY is PASSING from rarer to DENSER MEDIUM so refracted ray moves away from the normal
