What is the distance between the first and second fringes produced by a diffraction grating having 5400 lines per centimeter for 610-nm light, if the screen is 1.20 m away? 0.39528 X What is the relationship for constructive interference for a diffraction grating? How is the distance between lines on the grating related to the number of lines per unit length? Is the number of lines on the grating such that you can use the approximation sin 0 ~ tan 0? m
