Waves on a String Video Lessons

Concept

# Problem: For waves on a string, there are two wave velocity formulas:v=(Wavelength)(frequency) andv=sqrt(Tension/u)→ for the variables T and f:1) how can you increase the variables in lab (what can you change on the string - remember the length of a string is a constant)2) explain what happens as a result of the change and why, to- speed- wavelength- u (mass per unit length of a string)- tension

###### Problem Details

For waves on a string, there are two wave velocity formulas:

v=(Wavelength)(frequency) and

v=sqrt(Tension/u)

→ for the variables T and f:

1) how can you increase the variables in lab (what can you change on the string - remember the length of a string is a constant)

2) explain what happens as a result of the change and why, to

- speed

- wavelength

- u (mass per unit length of a string)

- tension
