Two very narrow, parallel slits separated by a distance of 1.4 x 10-5m are illuminated by coherent, monochromatic light of wavelength 7.0 x 10-7m. a describe what is meant by coherent and monochromatic light. b draw a graph to show the intensity of light observed on a screen far from the slits. c by drawing another graph on the same axes, illustrate the effect on the intensity distribution of increasing the width of the slits to 2.8 x 10-5m.
