Physics Question on Refraction of Light
Two plane wavefronts of light, one incident on a thin convex lens and another on the refracting face of a term prism. After refraction at them, the emerging wavefronts respectively become
A
plane wavefront and plane wavefront
B
plane wavefront and spherical wavefront
C
spherical wavefront and plane wavefront
D
spherical wavefront and spherical wavefront
Answer
spherical wavefront and plane wavefront
Explanation
Solution
Two plane wavefronts of light one incident on a thin convex lens and another on the refracting face of a thin prism. After refraction at the two surfaces, the emerging wave respectively have spherical wavefront and plane wavefront are shown in the diagrams (a) and (b).
