Hello, I need help with a light wave interference question.
Q: Imagine you are trying to measure the width of a single strand of spider web. You have fastened the web to the slide horizontally. You illuminate the strand with a 650nm laser and project the resulting interference pattern onto the wall where you have fastened a piece of paper. Given that the strand is
65 μm wide and is located 2 meters from the wall, draw the resulting interference pattern you would see in. Draw the pattern to scale in the correct orientation. Include only the m=-2, -1, 0, 1, 2 maxima (bright spots). Indicate the distance between each adjacent maximum.
Usually I would say what I know and how I would approach this problem, but for this one I really am at a lost. Any help is greatly appreciated
