1.	In the experiment to trace the path of a ray of light through a parallel sided glass slab, a student measured the angles of refraction for three different angles of incidence. He will find that :
Answer» angle of refraction is always equal to the angle of INCIDENCE angle of refraction is always smaller than the angle of incidence angle of refraction is always greater than the angle of incidence angle of refraction can be smaller or greater than the angle of incidence depending on the refractive INDEX of GLASS slab Solution :NA
