I am stuck on a question about standing waves:
'The diagram below show's Melde's experiment and demonstartion of a stationary wave on a string'
The string has 3 full wavelengths shown, and 3 points are marked:
Point A is on an antinode, Point B is on the same antinode, but very fractionally to the right, and point C is on an antinode out of phase (see the attachment for a similar diagram)  A is in red, B is in black, C is in blue
The first question is easy:
"State whether the following paris of points on the string are in phase, in antiphase, or neither in phase nor antiphase
A and B  I put that they are both in phase
A and C  I put that they are in antiphase
The next question (the tough nut):
"Describe briefly how you could check this experimentally"
I have no idea!
Any form of help/guidance will be much appreciated
