The equation of the progressive wave is   $y= 3sin \left[ \pi\left(\frac{t}{3}-\frac{x}{5}\right)+\frac{\pi}{4}\right]$, where x and y are in metre and time in second .Which of the following is correct?

Answer:

Explanation:

 Compare the given equation with the  standard  equation of wave motion,

   $Y= A \sin\left[2\pi\left(\frac{t}{T}-\frac{x}{\lambda}\right)\times\frac{\pi}{4}\right]$

where, A  and $\lambda$ are amplitude and wave length respectively

 Amplitude , A= 3m

Wavelength , $\lambda$ =10 m
