Phenomenon of refraction can be explained on the basis of wave theory of light. Let XY be the plane refracting surface separating two media air and glass of respectively. indices μ1 and μ2 refractive. ... According to Huygens' principle, secondary wavelets will originate from A1 and will spread over a hemisphere in glass.:-) :-) ---
A light ray incident upon a reflective surface will be reflected at an angle equal to the incident angle. Both angles are typically measured with respect to the normal to the surface. This law of reflection can be derived from Fermat's principle.

- Similarly the incident ray, the refracted ray and the normal at the point of incidence lie in the same plane i.e. plane of the paper.
- Hence laws of refraction are proved.
- Thus the phenomenon of refraction is explained on the basis of the Huygens' wave theory of light.
