Given below are two statements:
Statement I: A plane wave after passing through prism remains as plane wave but passing through small pin hole may become spherical wave.Statement II: The curvature of a spherical wave emerging from a slit will increase for increasing slit width.In the light of the above statements, choose the correct answer from the options given below
Official answer
From NTA’s final answer key for this paper.
(3)
Statement I is true but Statement II is false
