Homework Statement
Given: angular frequency=2000pi
phase velocity=320m/s
period=? unknown
Homework Equations
f=w/2pi; w=omega. T=1/f. phase velocity = lambda/T
The Attempt at a Solution
i don't know what the sgnificance of the phase velocity is. this is because from 1/T = w/2pi, i can already compute the T=2pi/w or 1x10^-3. unfortunately, it s not in the choices. can someone help? thanks!
