Ultraviolet light of wavelength is incident on a diffraction grating with slit spacing and forms an interference pattern on a screen a distance away. The angular positions of the interference maxima are large. The locations of the bright fringes are marked on the screen. Now red light of wavelength is used with a diffraction grating to form another diffraction pattern on the screen. Will the bright fringes of this pattern be located at the marks on the screen if (a) the screen is moved to a distance from the grating, (b) the screen is moved to a distance from the grating, (c) the grating is replaced with one of slit spacing , (d) the grating is replaced with one slit spacing , or (e) nothing is changed?
