2. When a tennis racket strikes a tennis ball, the racket begins to vibrate. There is a set of selected frequencies at which the racket will tend to vibrate. Each frequency in the set is characterized by a particular standing wave pattern. The diagrams below show the three of the more common standing wave patterns for the vibrations of a tennis racket. In each diagram, hash marks are placed at the positions of all nodes and antinodes; label these nodes (N) and antinodes (AN). 11111111 Pattern A Pattern B λA |-- Pattern C Compare the wavelength of pattern A to the wavelength of pattern B. Make your comparison both qualitative and quantitative. Repeat for pattern C. λA ^B (<,>,=) _^℃ (<,>,=) 2A = AB (2, 3, 4, etc.) ^A = AC (2, 3, 4, etc.) When the racket vibrates as in pattern A, its frequency of vibration is approximately 30 Hz. Determine the frequency of vibration of the racket when it vibrates as in pattern B and pattern C. Hz fB = fc = Hz
