The figure shows a snap photogaraph of a vibrating siring ai l = 0. The particle P is observed moving up with velocity 20sqrt(3) cm/s. The tangent at P makes an aggie 60IJ with x-axis. The mass per unit length of string is 50 g/m:

Answer»

wave is moving along positive x-direction
The EQUATION of the wave is `y = 0.4 sin(10 PI t - pi/2x)`
Total ENERGY carried by the wave per cycle of the striiig is`1.6 xx 10^(-5)` J
The equation of the wave is `y= 4 mm sin (10 pit + pi/2 x + pi/4)`
