[" If the wave equation is "^(*)],[qquad y=0.08sin(2 pi)/(lambda)(200t-R)" the velocity of the wave "]

If the wave equation y= 0.08 sin (2 pi)/(lambda) (200t-x) then the velocity of the wave will be

From a wave equation y= 0.5 sin ((2pi)/3.2)(64t-x). the frequency of the wave is

From a wave equation y= 0.5 sin ((2pi)/3.2)(64t-x). the frequency of the wave is

A wave is given by the equation y=A sin 2pi ("f"t-x//lambda) Its maximum particle velocity is four times the wave velocity, when lambda is
