Here's my question (parts a-c are correct, but I need help with d and e):
Transverse waves on a string have a wave speed 8 m/s, amplitude .09 m, and a wavelength .38 m. The waves travel in the -x direction, and at t=0 the x=0 end of the string has zero displacement and is moving in the +y direction.
Calculator should be in radians
a) Find the following properties of these waves.
Frequency 21.05 Hz
Period .0475 seconds
Wave number 16.53 rad/m
b) Complete the wave function describing the wave
.09m*sin 2pi[(21.05 Hz)t+(2.63/m)x]
or (without units) = .09 Sin 2pi[21.05*t+2.63x]
c) Find the transverse displacement of a particle at x=.36m at time t=.15s
y=5.5702 cm
Everything is correct up to this point
Here's what I have Wrong:
d) How much time must elapse from the instant in part c until the particle at x=.36 m next has zero displacement?
e) How much additional time must elapse from the instant in part d until the next time the particle has zero displacement?
If anyone oculd help me, I would greatly appreciate it!
Thanks!
