Missing Wavelength in Front of One Slit in YDSE

Category : JEE Main & Advanced

Suppose P is a point of observation infront of slit \[{{S}_{1}}\] as shown

Missing wavelength at P    

\[\lambda =\frac{{{d}^{\mathbf{2}}}}{\mathbf{(2}n-\mathbf{1)}D}\]

By putting \[n=1,\,2,\,3\,....\] Missing wavelengths are

\[\lambda =\frac{{{d}^{2}}}{D},\,\frac{{{d}^{2}}}{3D},\,\frac{{{d}^{2}}}{5D}....\]
