- Homework Statement
- The diagram shows a stationary wave on a string at one instant in time. box
P, Q and R are three points on the string.
- Relevant Equations
- none that I think are needed...
I think I understand that points P and R are pi radians out of phase - reaching their max/min at the same time.
But are P and Q in anti phase?
What is antiphase exactly - is it when they are 180deg out of phase - or is it when they are anything other than totally in phase? I seem to find conflicting answers
