Homework Statement
Hi,
In my textbook, it says that waves superposing to form stationary waves, in addition to being in opposite directions, should have the same frequency and ideally the same amplitude - why the 'ideally' and why is having the same amplitude important? Is it because then we don't get nodes of zero displacement? If so, why is that?
Further, it also says that because they have the same frequency, at certain points they are in antiphase; can't two waves of different frequencies be in antiphase at a point though?
Thanks :)
