A thread must have a uniform thickness of 0.650 mm. To check the thickness of the thread, you can illuminate it with a laser of wavelength 496.5 nm. A diffraction pattern like the one produced by a single slit forms on a screen. (a) If the screen is 2.80 m from the thread, how far apart are the fifth-order minima from one another? cm (b) If the thread's thickness increases by 20%, how far apart will the fifth-order minima be? cm A thread must have a uniform thickness of 0.650 mm.
