Asked by Anna
A wave on a string is described by the following equation (assume the +x direction is to the right).
y = (18 cm) cos[ðx/(5.3 cm) - ð t/(14 s)]
What is its period?
What is its speed?
In which direction does the wave travel? To the left or to the right?

for period, choose x=0. then when the second term is 2PI, t=period.
