283499 A parallel beam of light of wavelength \(\lambda\) is incident normally on a narrow slit. A diffraction pattern formed on a screen placed perpendicular to the direction of the incident beam. At the second minimum of the diffraction pattern, the phase difference between the rays coming from the two edges of slit is

283501 Assertion: The clouds in sky generally appear to be whitish.
Reason: Diffraction due to clouds is efficient in equal measure at all wavelengths.

283505 A Single slit Fraunhoffer diffraction pattern is formed with white light. For what wavelength of light the third secondary maximum in the diffraction pattern coincides with the second secondary maximum in the pattern for red light of wavelength \(6500 \AA\) ?

283507 The Fraunhoffer 'diffraction' pattern of a single slit is formed in the focal plane of a lens of focal length \(1 \mathrm{~m}\). The width of slit is \(0.3 \mathrm{~mm}\). If third minimum is formed at a distance of \(5 \mathrm{~mm}\) from central maximum, then wavelength of light will
