Q1 of 97 Page 323

A wave pulse passing on a string with a speed of 40 cm s−1 in the negative x-direction has its maximum at x = 0 at t = 0. Where will this maximum be located at t = 5 s?

At x = − 2 m


Speed is 40 cms-1= 0.4ms-1


Now,






The wave is travelling in the negative x direction and got started from x=0 at t=0. So the position of maxima at t=5 will be at x=-2m.
