The figure shows a surface XY separating two transparent media, medium-1 and medium-2. The lines \( a b \) and cd represent wavefronts of a light wave traveling in medium-1 and incident on \( \mathrm{XY} \). The lines ef
\( P \) and gh represent wavefronts of the light wave in medium- 2 after refraction.

W
Light travels as a
(A) parallel beam in each medium
(B) convergent beam in each medium
(C) divergent beam in each medium
- (D) divergent beam in one medium and convergent beam in the other medium
