A wave pulse on a string has the dimension shown in figure. The wave speed is v = 1 cm/. If point O is a free end, the shape of wave at time t = 3 is
Correct option : (d)
Explanation:
At t = 3 *, the wave pulse will reach at the free end. At the free end the displacement after superposition becomes
R = 2 A = 2 × 1 = 2 cm.
