In Young's double slit experiment, if the source of light changes from orange to blue, then

Options

  1. Athe central bright fringe will become a dark fringe
  2. Bthe distance between consecutive fringes will decrease
  3. Cthe distance between consecutive fringes will increase.
  4. Dthe intensity of the minima will increase.

Correct answer

B. the distance between consecutive fringes will decrease

Step-by-step solution

We know that in Young's double slit experiment, fringe width = D d , Since, _ blue _ orange Thus, _ blue _ orange In Young's double slit experiment, if the source of light changes from orange to blue, then distance between the consecutive fringes will decrease.
