A) 100 m/s
B) 200 m/s
C) 400 m/s
D) 5 mm/s
Correct Answer: B
Solution :
Given equation is \[y=0.3\,\sin (314t-1.57x)\] ...(1) Standard equation is \[y=A\,\,\sin \,(\omega t\,kx)\] ...(2) Comparing (1) and (2), we get \[\omega \]=314 rad/s \[k=1.57\,{{m}^{-1}}\] \[\therefore \]Velocity of wave, \[\upsilon =\frac{\omega }{k}=\frac{314}{1.57}\] \[=200\,m/s\]You need to login to perform this action.
