Question
A wave pulse on a string has the dimension shown in figure. The waves speed is v = 1 cm/s. If point O is a free end. The shape of wave at time t = 3 s is :
Options
A.
B.
C.
D.
Solution
Sol. νw = 1 cm/s, At t = 3s, The crest will reach at O. As O is a free end, so amplitude will double at this point.
