Question

If Youngs double slit experiment is performed in water instead of air, then : (A) no fringes would be seen (B) fringe width would decrease (C) fringe width would increase (D) fringe width would remain unchanged

Fringe width, β =(Dλ /d) or β propto λ If the experiment is performed in water, wavelength λ decreases, so, fringe width also decreases.

Q. If Youngs double slit experiment is performed in water instead of air, then :

no fringes would be seen

fringe width would decrease

fringe width would increase

fringe width would remain unchanged

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

Fringe width, β=dDλ​ or β∝λ If the experiment is performed in water, wavelength λ decreases, so, fringe width also decreases.
