If Young's double slit experiment is performed in water instead of air, then

Options

  1. Ano fringes would be seen
  2. Bfringe width would decrease
  3. Cfringe width would increase
  4. Dfringe width would remain unchanged

Correct answer

B. fringe width would decrease

Step-by-step solution

Fringe width, β=Dλd\beta=\frac{D \lambda}{d} or β∝λ\beta \propto \lambda If the experiment is performed in water, wavelength λ\lambda decreases, so, fringe width also decreases.
