(i) it \[\frac{\lambda }{2\pi }>{{A}_{0}},\] maximum particle speed is more than the wave speed |
(ii) if \[\frac{\lambda }{2\pi }={{A}_{0}},\] maximum particle speed is equal to the wave speed |
(iii) In harmonic wave, wave velocity is constant |
(iv) In harmonic wave, particle speed is constant |
The correct statements are |
A) (i) and (iii)
B) (ii) and (iii)
C) (i) and (iv)
D) (ii) and (iv)
Correct Answer: B
Solution :
[b] Maximum particle speed \[=\omega {{A}_{0}}\] Wave velocity \[=\left( \frac{\omega }{K} \right)\Rightarrow \frac{\omega }{K}=\omega {{A}_{0}}=\frac{\lambda }{2\pi }={{A}_{0}}\] For a medium wave, velocity is constant.You need to login to perform this action.
