A) its wavelength is 2 units
B) it is travelling in the positive x-direction
C) wave velocity is 1.5 units
D) time period of SHM is 1 s
Correct Answer: A
Solution :
The standard equation is \[y=a\sin 2\pi \left( \frac{t}{T}-\frac{x}{\lambda }+\phi \right)\] ?. (i) Dividing and multiplying the given equation by \[2\pi ,\]we get \[y=a\sin 2\pi \left( \frac{10}{2}x+\frac{11}{2}t+\frac{\pi }{3} \right)\] ...(ii) On comparing Eqs. (i) and (ii), we get \[\lambda =2\text{ }units\]
