1.	Fig. shows a surface XY separating two transparent media, medium 1 and medium 2. Lines ab and cd represent wavefronts of a light wave travelling in medium 1 and incident on XY. Line ef and gh represent wavefront of the light wave in medium 2 after rafraciton. Light travel as aA. parallel beam in each mediumB. convergent beam in each mediumC. divergent beam in each mediumD. divergent beam in one medium and convergent beam in the other medium
Answer» Correct Answer - a Wavefronts are parallel in both media. Therefore, light which is perpendicular to the wavefront travels as a parallel beam in each medium.
