Longitudinal wave on a spring.

Version 0.1 4-5-09

Pitch of spring

p=slider([0,40,100])

Amplitude, wave number, and angular frequency of wave:

A=slider([0,0.5,100])

k=slider([0,2])

W=slider([0,2])

vector(x,y,z)=vector(cos([p*t]),sin([p*t]),t+A*sin([k*t-(W*n)]))

Highlight short stretch of spring:

h=slider([1,45])

vector(x,y,z)=vector(cos([p*t/h]),sin([p*t/h]),t/h+A*sin([k*t/h-(W*n)]))

Relaxed spring:

vector(x,y,z)=vector(cos([p*t]),sin([p*t]),t)
