Homework Statement
it's stated that 2.5meters separated a trough and an adjacent crest of surfae wave on a lke.
Homework Equations
The Attempt at a Solution
At first I thought if the trough to th crest is 2.5meters then i would double that to get the wavelenght from crest to crest. But then when I drew another wave picture, the 2.5 can be the amplitude? so that would make me taking half of the 2.5meters instead?? I think my problrm is not understanding what that statmnt is trying to say. I'm unsure if I would multiply 2.5m by two or divide by half. thanks
