A parallel beam of light of wavelength l is incident normally on a narrow slit. A diffraction pattern is 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

A parallel beam of monochromatic light is incident normally on a slit. The diffraction parttern is observed on a screen placed at the focal plane of convex lens. If the slit width is increased , the central maximum of the diffraction pattern will

Light of wavelength lambda=5000Å falls normally on a narrow slit. A screen is placed at a distance of 1m from the slit and perpendicular to the direction of light. The first minima of the diffraction pattern is situated at 5mm from the centre of central maximum. The width of the slit is
