Two Pulses with the same amplitude are moving toward each other on a rope. what happens?

Question

a. they will reflect off each other and reverse their direction
b.they will cancel out, leaving no pulses in the rope
c.they will combine to porm a pulse of twice the amplitude
d.they will pass through each other.
e.they will combine to form a standing wave

Answer 1

The best answer is that they will move through each other. If they meet crest to crest they will add. If they meet crest to trough they will cancel each other, but in either case they will move through.

Answer 2

Depends. If they are out of phase, they will cancel each other out. If they are in phase, the resulting amplitude will double upon meeting.

Hope this helps
