A) 100 Hz, 1.7 m, 170 m/s
B) 150 Hz, 2.4 m, 200 m/s
C) 80 Hz, 1.1 m, 90 m/s
D) 120 Hz, 1.25 m, 207 m/s
Correct Answer: A
Solution :
Comparing the given equation with standard equation We get \[\omega =2\pi n=200\pi \] Þ n = 100 Hz \[k=\frac{20\pi }{17}\] Þ \[\lambda =\frac{2\pi }{k}=\frac{2\pi }{20\pi /17}=1.7\,m\] and \[v=\frac{\omega }{k}=\frac{200\,\pi }{20\pi /17}=170\,m/s.\]You need to login to perform this action.
