I am shining light of 532 nm wavelength perpendicularly onto a one-dimensional array of scatterers with spacing 1.5 microns. I am looking at the back-scattered light on a screen a long distance away from the scattering array. How many diffraction "spots" should I see on the screen? Please enter an integer number.
help me to solve
