In Young's double slit experiment, the fifth maximum with wavelength ' $λ_{1}$ ' is at a distance ' $y_{1}$ ' and the same maximum with wavelength ' $λ_{2}$ ' is at a distance ' $y_{2}$ ' measured from the central bright band. Then $\frac{y _{1}}{y _{2}}$ is equal to [D and $d$ are constant]

Options:

Answer:

Solution:

The equations for the position of the fringe from the central maxima are given as $y_{1} y_{2} ∴ \frac{y _{1}}{y _{2}} = \frac{5 λ _{1} D}{d} = \frac{5 λ _{2} D}{d} = \frac{λ _{1}}{λ _{2}}$
