Figure (15-E1) shows a wave pulse at t = 0. The pulse moves to the right with a speed of 10 cm s−1. Sketch the shape of the string at t = 1 s, 2 s and 3 s.
The speed is 10 cms-1
So, at 1 s the pulse will be at 10 cm.
At 2 s the pulse will be at
X=2x10cm
=20 cm
At 2 s the pulse will be at
X=3x10cm
=30 cm
