JEE Mains · Physics · STD 12 - 10. Wave optics
In Young's double slit experiment, if the source of light changes from orange to blue then
- A the central bright fringe will become a dark fringe.
- B the distance between consecutive fringes will decrease.
- C the distance between consecutive fringes will increase.
- D the intensity of the minima will increase.
Answer & Solution
Correct Answer
(B) the distance between consecutive fringes will decrease.
Step-by-step Solution
Detailed explanation
Fringe width \(\beta=\frac{\lambda D}{d}\) as \(\lambda\) decreases, \(\beta\) also decreases
