Homework Statement
A 403 Hz wave travels at 200 m/s along a wire.
a)At a given time, the distance between points that differ in phase by 1.9 rad is ___ m.
b)At a given position, the change in phase during an interval of 4.8 ms is ___ rad.
Homework Equations
V=w/k
w=2pif
The Attempt at a Solution
I 've already solved for a), it was pretty straight forward. Now, I'm stuck on b)
w=2pif
=2pi*403
=806pi
v=w/k
k=w/v
=806pi/200
=4.03pi
delta phi = x/k
= 1.9/4.03pi
=0.15m
this was for number 1... now I'm stuck on b)
pls help...
