The equation of a progressive wave is given by $y = a \sin (628 t - 31.4 x)$ . If the distances are expressed in $cm$ and time in seconds, then the wave velocity will be

Options:

Answer:

Solution:

Wave equation is $y = a \sin (628 t - 31.4 x)$

Wave speed is given by,

$v = \frac{Co efficient of t}{Co efficient of x}$

$v = \frac{628}{31.4}$

$v = 20 c m s^{- 1}$
