- 13. Suppose that you have a laser of wavelength 2 = 450 nm, and a single slit with a width of a = 0.16 mm. You plan to place the slit exactly L = 1.00 m away from a viewing screen, but you want to predict the positions of the dark fringes in advance. First, let's check if the small-angle approximation applies to this situation. a. Use på a sin 0 to calculate the angle 8₁ for the first order (p = 1) dark fringes: = b. Calculate sin 0₁: c. Calculate tan 0₁: d. Compare the values for sin 0, and tan 8₁. Are these approximately equal? If so, then we can use the small angle approximation 0, (rad) ≈ P²P for further R a L calculations, and the dark fringes should be equally spaced.

- reflective diffraction grating is to have a grating spacing of 3 microns. a. If you want the 2nd order 450 nm to be retroreflected (Littrow mount), what is the blaze angle? b. What is the angle between the 450 nm 2nd order and 451 nm 2nd order reflections?1. a. If a piece of glass (n = 1.5) is coated with a transparent plastic (n = 2.0), will there be a phase shift in either of the beams reflecting off the interfaces (air/plastic and plastic/glass)? How can you tell, without doing the experiment, whether or not there will be a phase shift in either beam? Be specific about what rays are reflecting off what materials. b. So what thickness or thicknesses give the maximum reflection? What thickness or thicknesses (hint: it's thicknesses) give the minimum reflection? Assume that a light of wavelength 500. nm is used, and you may leave the answer in nm. Yes, this is a choice between equations 35.17 and 35.18, but your answer to part a should be helpful in deciding which set.A diffraction grating having 4000 lines/cm is illuminated with 500-nm light.
