Intense white light is incident on a diffraction grating that has 454 lines/mm. (a) What is the highest order in which the complete visible spectrum can be seen with this grating? (Enter 1 for first order, 2 for second order, etc.) (b) What is the angular separation between the violet edge (400 nm) and the red edge (700 nm) of the first order spectrum produced by the grating? answer in °

The coherence length of an ordinary white light source can be increased if we place a color filter in front of the source, so that the light that passes through the filter is somewhat monochromatic. The minimum wavelength of the emerging light is 546 nm. What is the maximum wavelength in order for the coherence length to be 0.1110 mm?

DS-3 Coherent, monochromatic light goes through a pair of slits which are spaced a distance 0.600 mm apart, and the interference pattern is projected onto a screen. You notice that there are 11 bright fringes within the central diffraction maximum. What is the width of each slit (a)?
