11. Coherent light of wavelength 528 nm (1 nm = 10-9 m) is sent through two parallel slits in anopaque material and projected onto a screen 4.00 m away. Each slit has width D = 1.70 µm (1um = 10–6 m). Their centers are d = 10.7 µm apart. As seen in the class demo and in the figurebelow, a double-slit interference pattern appears within a single slit diffraction pattern.a) What are the locations of the first two double-slit maxima to the right of the central maximum?Hint: use the slit spacing d for double slit interference.b) What are the locations of the first two minima to the right in the single slit diffraction pattern?Hint: use the width D of each slit for single slit diffraction.c) How many double slit interference maxima fit into the central diffraction maximum (i.e., howmany double slit maxima are there between the dark bands on either side of the centraldiffraction pattern)?

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. S 2015 #10772/ 754911 My PORTALLA 1500 ALTERNA
