4) Two narrow slits are separated by a distance d. Their interference pattern is to be observed on a screen a large distance L away. a) Calculate the spacing y of the maxima of the screen for light of wavelength 500 nm when L = 1 m and d = 1 cm. b) Would you expect to observe the interference of light on the screen for this situation? Explain. c) How close together should the slits be placed for the maxima to be separated by 1 mm for this wavelength and screen distance.

Two narrow slits are used to produce a double-slit interference pattern with monochromatic light. The slits are separated by 8 mm, and the interference pattern is projected onto a screen 7 m away from the slits. The central bright fringe is at a certain spot on the screen. Using a ruler with one end placed at the central fringe, you move along the ruler passing by two more bright fringes and find that the next bright fringe is 23.5 mm...
