y= 10^-4 sin (100t -x/10)
dy/dt = v = 10^-4 cos( 100t -x/10) 100
= 10^-2 cos (100t -x/10)
but its velocity of particle
VELOCITY OF WAVE = w/k
w = 100
k = 1/10
V = 100/1/10
V = 1000
dy/dt = v = 10^-4 cos( 100t -x/10) 100
= 10^-2 cos (100t -x/10)
but its velocity of particle
VELOCITY OF WAVE = w/k
w = 100
k = 1/10
V = 100/1/10
V = 1000
