Superposition and Interference Single-color thin-film interference • Reflection from the upper and lower surfaces of a wedge of air between two glass plates © 2010 Pearson Education, Inc.
Superposition and Interference colors by reflection from thin films. • The thin film of gasoline is just the right thickness to result in the destructive interference of blue light. © 2010 Pearson Education, Inc.
Superposition and Interference Diffraction grating • Composed of a large number of close, equally spaced slits for analyzing light source • Produced by spectrometers that disperse white light into colors © 2010 Pearson Education, Inc.
Superposition and Interference CHECK YOUR NEIGHBOR If the thin film of gasoline was a bit thinner, the wavelength to be canceled would be A. B. C. D. shorter than that of blue. longer than that of blue. white. None of the above. © 2010 Pearson Education, Inc.
Superposition and Interference CHECK YOUR ANSWER If the thin film of gasoline was a bit thinner, the wavelength to be canceled would be A. B. C. D. shorter than that of blue. longer than that of blue. white. None of the above. © 2010 Pearson Education, Inc.
Superposition and Interference CHECK YOUR NEIGHBOR If violet light were canceled by the double reflection of sunlight from gasoline on a wet surface, the resulting color would likely be A. B. C. D. red. orange. green. violet. © 2010 Pearson Education, Inc.
Superposition and Interference CHECK YOUR ANSWER If violet light were canceled by the double reflection of sunlight from gasoline on a wet surface, the resulting color would likely be A. B. C. D. red. orange. green. violet. Explanation: Orange is the complementary color of violet. © 2010 Pearson Education, Inc.
Superposition and Interference CHECK YOUR NEIGHBOR If you see the color blue reflected in the interference from gasoline on water, and you lower your head so a greater angle from the normal results, you’ll likely see a color having a wavelength A. B. C. D. shorter than that of blue. longer than that of blue. with a white appearance. None of the above. © 2010 Pearson Education, Inc.
Superposition and Interference CHECK YOUR ANSWER If you see the color blue reflected in the interference from gasoline on water, and you lower your head so a greater angle from the normal results, you’ll likely see a color having a wavelength A. B. C. D. shorter than that of blue. longer than that of blue. with a white appearance. None of the above. Explanation: The path through the gasoline would be longer, and a longer wavelength would be canceled. The result of a long wave being canceled is a shorter wave. © 2010 Pearson Education, Inc.
