Light of wavelength 540nm from a green laser is incident on two slits separated by 0.50mm; the light reaches a distant square screen 50cm x 50 cm that is 1m away from the slits. Describe quantitatively the pattern that you will see. Answer the following and determine the distance between the light and dark spots on the screen. a) Sketch and translate. Visualize the situation and sketch it. Translate givens into physical quantities. b) Simplify and diagram. Decide if the small angle approximation is appropriate. Represent the situation with a ray diagram (also showing waves along the rays) showing the path of light waves and the extra distance. (Use a location that will be helpful for answering the question.) c) Represent mathematically. Describe the diagram mathematically. d) Solve and evaluate. Solve the problem and decide if the answer makes sense
