If the screen is moved away from the plane of the slits in a Young's double slit experiment, then the:

Options

  1. Aangular separation of the fringes increases
  2. Bangular separation of the fringes decreases
  3. Clinear separation of the fringes increases
  4. Dlinear separation of the fringes decreases

Correct answer

C. linear separation of the fringes increases

Step-by-step solution

As per YDSE, x= D d , (where, symbols have their usual meanings) If the screen is moving away from the slits then D increases, and hence the fringe width (x) increases.
