Sodium light that has a wavelength equal to falls normally
Chapter , Problem 69(choose chapter or problem)
Sodium light that has a wavelength equal to falls normally on a diffraction grating ruled with 4000 lines per centimeter. The Fraunhofer diffraction pattern is projected onto a screen a distance of from the grating by a focal-length lens that is placed immediately in front of the grating. Find (a) the distances of the first and second order intensity maxima from the central intensity maximum, (b) the width of the central maximum, and (c) the resolution in the first order. (Assume the entire grating is illuminated.)
