Comparing this equation with $y = a\sin 2\pi \left( {\frac{t}{T} - \frac{x}{\lambda }} \right)$
$v = \frac{{{\rm{Co - efficient \,of\, }}t}}{{{\rm{Co - efficient\, of\, }}x}} = \frac{{1/0.02}}{{1/100}}$

Statement$-2:$ Intensity of waves of given frequency in same medium is proportional to square of amplitude only.
