Question

The figure shown at time `t = 0` second, a rectangular and triangular pulse on a uniform wire are approcaching other. The pulse speed is `0.5 cm//s` . The resultant pulse at `t = 2` second is

Answer 1

In 2 s each pulse will travel a distance of 1 cm.
The two pulses overlap between 0 and 1 cm as shown in figure. So, `A_1 and A_2` can be added as
shown in Fig. (c).
