A diffraction pattern is obtained by making blue light incident on a narrow slit. If blue light is replaced by red light then
- A there is no change in diffraction pattern.
- B diffraction band become broader.
- C diffraction bands become broader.
- D diffraction bands become narrower.
Answer & Solution
Correct Answer
(C) diffraction bands become broader.
Step-by-step Solution
Detailed explanation
The correct option is (C).
Concept Based: The width of the diffraction bands is directly proportional to the wavelength thus, a minor broadening is observed.
