The displacement of a particle is given by `y= 5 xx 10 ^(-4) sin (100 t-50 x)` , where x is in meter and t in sec, find out the velocity of the wave

The displacement of a particle in a medium can be expressed as y=10^(-6)sin(100t+20x+pi//4), where x is in metre and t is in second. What is the speed of the wave?

The equation of a wave is given by y=a sin (100t-x/10) where x and y are in metre an t in second, the velocity of wave is

The equation of a wave is given by y=a sin (100t-x/10) where x and y are in metre an t in second, the velocity of wave is

The equation of progressive wave is y=a sin (200 t-x) . where x is in meter and t is in second. The velocity of wave is
