In the far field diffraction pattern of a single slit under polychromatic illumination, the first minimum with the wavelength \[{{\lambda }_{1}}\] is found to be coincident with the third maximum at \[{{\lambda }_{2}}\]. So

• A.            \[3{{\lambda }_{1}}=0.3{{\lambda }_{2}}\]                 
• B.            \[3{{\lambda }_{1}}={{\lambda }_{2}}\]
• C.            \[{{\lambda }_{1}}=3.5{{\lambda }_{2}}\]                    
• D.            \[0.3{{\lambda }_{1}}=3{{\lambda }_{2}}\]
