Q1. The sodium D line is a doublet consisting of two wavelengths, 588.995 and 589.592 nm. Calculate the angular separation between these two lines in the first-order spectrum for a grating with 4000 lines per centimeter. Repeat for the second order.Q2. When red light of wavelength 620 nm falls on a single slit, it creates a central diffraction maximum that is 8.80 mm wide on a screen 2.00 m away. How wide is the slit? How wide will the central peak be if the red light is replaced with a blue light of wavelength 500 nm?
