Question 452: Wave Optics

Question

The figure shows surface XY separating two transparent media, medium -1 and medium -2 . The lines ab and cd represent wavefronts of a light wave traveling in medium -1 and incident on X Y. The lines ef and gh represent wavefronts of the light wave in medium -2 after refraction.

Accepted Answer

The gap between consecutive wave fronts in medium 2 is less than that in medium 1. Therefore, wavelength of light in medium 2 in less than that in medium 1. Therefore, speed of light is more in medium 1 and less in medium 2.

Answer

the same in medium-1 and medium-2

Answer

larger in medium-1 than in medium-2

Answer

larger in medium-2 than in medium-1

Answer

different at b and d
