- Diffraction can be used to provide a quick test of the size of red blood cells. Blood is smeared onto a slide, and a laser shines through the slide. The size of the cells is very consistent, so the multiple diffraction patterns overlap and produce an overall pattern that is similar to what a single cell would produce. Ideally, the diameter of a red blood cell should be between 7.5 and 8.0 μm. If a 633 nm laser shines through a slide and produces a pattern on a screen 24.0 cm distant, what range of sizes of the central maximum should be expected? Values outside this range might indicate a health concern and warrant further study.Fringes in the Thomas Young experiment are produced using sodium light of wavelength 495 nm and two slits which are 1.2 mm apart. If the fringes are formed on a screen 1.0 m away from the slits, how far is the third order bright fringe from the middle of the screen? Give your answer in millimeters (mm).The interference figure of a set of double slits is measured at a stop.
