Question #41540

if there is a crest at x=3m at time t, find three other positions of the crest at that instant?

Expert's answer

We will think that wave is started form point = 0 (because it doesn`t say in what point it started).

If the crest is at x = 3m, that is point x =¼. That`s why the period will be 12m.

So with the period 12m the crest will repeat.

Answer: So the first three is 15m, 27m and 39m.
