Amonochromatic light passes through a narrow slit and forms a diffraction pattern on a screen behind the slit. as the wavelength of the light decreases, the diffraction patterna)spreads out with all the fringes getting wider. b)remains unchangedc)spreads out with all the fringes getting alternately wider and then narrower. d)becomes dimmere)shrinks with all the fringes getting narrower.
