A single slit diffraction pattern is obtained using a beam of red light. If red light is replaced by blue light then
- A the diffraction pattern will disappear
- B fringes will become narrower and crowded together
- C fringes will become broader and will be further apart
- D there is no change in the diffraction pattern
Answer & Solution
Correct Answer
(B) fringes will become narrower and crowded together
Step-by-step Solution
Detailed explanation
Fringe width \(\propto \lambda \therefore\) Fringes will be narrower and crowed.
