Explain the refraction of plane wavefront of light through a prism.

Text Solution

Verified by Experts

The secondary wavelets form B will travel almost the whole distance inside the prism to reach the point C. But the secondary wavelets from K will travel the whole distance in air before it is incident on the prism at A. The points K and B are phase, and so do L and C. LC and KB represent the plane wavefronts.
