Question

Two pulses are started on a stretched string. An upward pulse is started on the right that moves to the left. At the same instant, a downward pulse is started on the left that moves to the right. At t

a) Both pulses pass through each other without any interaction
b) The pulses annihilate each other
c) The pulses reflect off each other
d) The pulses continue moving in their respective directions

Answer 1

When two pulses traveling in opposite directions on a stretched string pass through each other, they continue moving in their respective directions without any interaction.

Step-by-step explanation:

The correct answer is d) The pulses continue moving in their respective directions.

When two pulses traveling in opposite directions on a stretched string pass through each other, they continue moving in their original directions without any interaction. This is because waves do not interact with each other directly; they simply pass through each other and continue on their way.

For example, if an upward pulse is started on the right side and a downward pulse is started on the left side of the string, at time t, the two pulses will overlap but continue moving in their respective directions. After the pulses pass through each other, their original amplitudes remain unchanged and they continue moving along the string.
