A diffraction pattern is obtained by making blue light incident on a narrow slit. If blue light is replaced by red light then
there is no change in diffraction pattern.
diffraction band disappear.
diffraction bands become broader.
diffraction bands become narrower.
Solution
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.
