QUESTION 4 2 points Save Answer In Investigation 4, you will be testing out the pattern produced by a diffraction grating. This is a device that consists of many hundreds of tiny slits, a small distance d apart from each other. When a laser shines on the grating, it produces a picture like the one seen here. Image of the pattern created by a diffraction grating The locations of these dots are theoretically found using the formula dsine = mi . The dots are labeled according to their order, m. The central dot is called the zeroth order dot (m = 0). The first ones to the left and right are m = 1. Further out are m = 2, etc. The definition of e can be seen in the picture below. Diffraction Screen Grating m Laser yo The distances between the slits in a diffraction grating are typically very small. This means that it is very difficult to get them to be precisely spaced. This is why manufacturers of diffraction gratings typically give a slit density, which is an average number of slits per mm. If you're given this type of density, how could you use that number to find the average distance between two adjacent slits? For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).
