How is the interference pattern affected when violet light replaces sodium light?

Options

  1. AThe fringes become brighter.
  2. BThe fringes become faint.
  3. CFringewidth decreases.
  4. DFringewidth increases.

Correct answer

C. Fringewidth decreases.

Step-by-step solution

In Young's double slit experiment, Fringe width W = D d As violet light is of smaller wavelength Fringe width decreases
