- Pattern A, a single-slit interference pattern viewed on a screen using a monochromatic source, is changed to pattern B. Both are shown below. Pattern A Pattern B Which of the following changes could explain the change in the pattern? a. The screen is moved closer. b. The width of the slit is increased. c. The frequency of the source is decreased. d. The wavelength of the source is decreased. e. The intensity of the source is increased.A bowl of water (n = 1.33) has a thin layer of grease (n = 1.60) floating on top of the water. When you illuminate the grease from above with monochromatic light, you get constructive reflection if the wavelength in air is 565 nm. Find the smallest possible thickness of the grease layer. Express your answer with the appropriate units. tmin = 8.83x10-8 m Submit Previous Answers Correct Correct answer is shown. Your answer 88.28 nm(=8.828x10-8 m) was either rounded differently or used a different number of significant figures than required for this part. Part H Find the second smallest possible thickness.
