Assertion : Intensity pattern of interference and diffraction are not same. Reason : When there are few sources of light, then the result is usually called interference but if there is a large number fo them, the word diffraction is more often used.

Visible light of wavelength 500 nm falls normally on a single slit and produces a diffraction pattern. It is found that the diffraction pattern is on a screen 1 m away from slit. If the first minimum is produced at a distance of 2.5 mm from the centre of screen, then the width of the slit is
