Q3 How do we mark the graph?(for momentum)

There is one question on antinode and node for tube
Where do we mark the anti node and node?
Anyone has notes on this section.


Is the book "PHYSICS for international as/a level good"?
Thank youuu :D

From the graph:
momentum of A before collision=6
momentum of B before collision=-4
momentum of A after collision=-3

According to conservation of momentum
momentum of B after collision=6-4+3=5
Since the collision of both particle takes same length of time i.e. tA=tB

Here is the graph

At open end there will be an anti node and a node in close end(piston).
Since the wavelength is 60cm and the tube is 45cm,therefore in the tube there is (3/4) of a wave.So there will another node and anti node in the middle some where.

If you don't understand please tell me :)

Sorry don't know about that book :(

All the notes are here
