A) The wavelength is 5 m
B) The frequency is 5 Hz
C) The velocity of propagation is 5 m/s
D) The wavelength is 0.2 m
Correct Answer: B
Solution :
Phase difference between two successive crest is 2p. Also, phase difference \[(\Delta \varphi )\]= \[\frac{2\pi }{T}\] time interval \[(\Delta t)\] Þ \[2\pi =\frac{2\pi }{T}\times 0.2\Rightarrow \frac{1}{T}=5{{\sec }^{-1}}\Rightarrow n=5\,Hz\]You need to login to perform this action.
