First secondary minima in case of diffraction due to single slit is obtained at a distance x from central maximum position, then
Find the right condition(s) for Fraunhofer diffraction due to a single slit
Assertion : The clouds in the sky generally appear to be whitish. Reason : Diffraction due to clouds is efficient in equal measures its all wavelengths.
The adjacent figure shows Fraunhoffer’s diffraction due to a single slit. If first minimum is obtained in the direction shown, then the path difference between rays 1 and 3 is
