Physics

Two separate experiments -- double-slit and diffraction grating-- use a 400-nm electromagnetic wave. In both experiments, a long,flat wall where the results are seen is located 2.00-m across fromthe slits/grating. The slit separation for the double-slitexperiment is 0.20mm. The diffraction grating has 1200 lines permm.

a. Calculate the distance between the first and second brightspots below the center line for each experiment. Compare youranswer for each experiment and explain how the pattern created onthe screen by the two experiments would differ.

b. If the slit-width is roughly the same for both, which patternwould have a brighter central maximum? Why?
