Wave Mechanics Question 613
Question: A wave travelling on a string is described by $ y=(x,t)=0.005,\sin ,(80.0x-3.0t) $ The period of the wave is
Options:
A) 3.00 s
B) 2.09 s
C) 0.48 s
D) 0.05 s
Show Answer
Answer:
Correct Answer: B
Solution:
[b] Time period, $ T=\frac{2\pi }{\omega } $ ; from given eqn. $ \omega =3.0,{{s}^{-1}} $ or $ T=\frac{2\pi }{3}=2.09s $
