Question

Two pulse travels in mutually opposite directions in a string with a speed of 2.5 cm/s as shown in the figure. Initially (at t = 0) the pulses are 10 cm apart. What will be the state of string after two seconds?
(a) figure a
(b) figure b
(c) figure c
(d) figure d

HeY Hello BroTher..

@Here is your answer..!!

#So, the answer is.. : Correct Answer ... "C"

Solution.. After two seconds each wave travel a distance of 2.5 ' 2 = 5 cm i. e. The two pulses will meet in mutually opposite phase and hence the amplitude of resultant will be zero.
