OPEN RESPONSES 1) In wave optics we considered the wave properties of light. Young's double slit experiment is used to create interference patterns on a screen (20 points) angele moniM ( O Slits xperim Screen a) A 1 = 650nm monochromatic light beam is sent through a double slit separated by 0.01mm. find the angle of incident(0) for m=2 second bright line due to constructive interference b) Assume the image above is showing the formation of the m=2 bright line at point P. If the screen is kept L = 0.5m away, find the y distance from the central maximum O location. c) If you replace the light beam with a 500 nm monochromatic green light beam while keeping everything else the same, how will the fringe separation (Ay) change? Will the fringe separation reduce, or will it increase? explain d) If the same monochromatic green light beam (1 = 500nm) is used with a single slit, instead of the double slits, you would observe a diffraction pattern with a wide central all of maximum. Find the width of the central maximum if the single slit width is 0.01 mm and the slit-screen distance is 0.5m. 2) An object is placed in front of a thin converging lens. The lens has a focal length of 4cm, and the object is kept 12 cm away from the lens.
