Question
The pulses shown in Figure $P 11.29$ (shown at time zero) are moving toward each other at speeds of $10 \mathrm{m} / \mathrm{s}$. Draw $y(x)$ graphs showing the resultant pulse at $0.10 \mathrm{s}, 0.20 \mathrm{s}$ and 0.30 s.
Step 1
Since the speed of the pulses is 10 m/s, in 0.10 s each pulse will have moved 1 m (10 m/s * 0.10 s = 1 m). Similarly, in 0.20 s each pulse will have moved 2 m, and in 0.30 s each pulse will have moved 3 m. Show more…
