Expert Solution & Answer
Chapter 14, Problem 7TE
Solution
To determine: The physical principle does these ridges of the features of peacock and hummingbird produce colors.
Answer:
The colours shown by the feathers of hummingbird and peacock are due to the phenomenon of diffraction.
Explanation:
Diffraction introduces to multiple events that happen when a wave encounters an obstacle or a slit. Here the colors of peacocks and hummingbirds are the result of diffraction through the layers present in the feathers.
Due to this principle, the peacock and hummingbird showcase their colors and patterns of colors where the ridges in the surface of feathers layers act as a diffraction grating.
Conclusion:
Therefore, the colours shown by the feathers of hummingbird and peacock are due to the phenomenon of diffraction.

The company is designing an electromagnetic propulsion system for a new roller coaster. A model of a substructure of the device appears in the figure below. Two parallel, horizontal rails extend from left to right, with one rail behind the other. A cylindrical rod rests on top of and perpendicular to the rails at their left ends. The distance between the rails is d and the length of the rails is L. The magnetic field vector B points vertically down, perpendicular to the rails. Within the rod, the current I flows out of the page, from the rail in the back toward the rail in the front. The rod is of length d = 1.00 m and mass m = 0.700 kg. The rod carries a current I = 100 A in the direction shown and rolls along the rails of length L = 20.0 m without slipping.
