Tension in a ropa to form transverse waves

Click For Summary
SUMMARY

The discussion focuses on calculating the tension required in a rope to produce transverse waves with a specific frequency and wavelength. The rope has a length of 2.20m and a mass of 0.100kg, while the desired frequency is 43.0Hz and the wavelength is 0.700m. The key equations utilized include the wave velocity equation, v = √(T/μ), and the relationship between wave velocity, frequency, and wavelength, v = λf. By substituting the known values into these equations, the tension T can be determined effectively.

PREREQUISITES
  • Understanding of wave mechanics, specifically transverse waves
  • Familiarity with the concepts of tension and mass per unit length (μ)
  • Knowledge of basic physics equations related to wave velocity
  • Ability to manipulate algebraic equations to solve for unknowns
NEXT STEPS
  • Learn about the relationship between tension and wave speed in strings
  • Study the derivation and application of the wave equation in different media
  • Explore the concept of mass per unit length (μ) and its impact on wave propagation
  • Investigate real-world applications of transverse waves in engineering and physics
USEFUL FOR

Students studying physics, particularly those focusing on wave mechanics, as well as educators seeking to explain the relationship between tension and wave properties in ropes and strings.

Homework Statement


With what tension must a rope with length 2.20m and mass 0.100kg be stretched for transverse waves of frequency 43.0Hz to have a wavelength of 0.700m?

The Attempt at a Solution


I am completely oblivious as to where to start this question. I always like to have an attempt at a solution when I post, unfortunately I don't know where to begin.
Any help with relevant equations would be greatly appreciated as my physics class has yet to cover relation between tension and transverse waves.
 
Physics news on Phys.org
After some rooting around and Wiki (how I love Wiki) I found that:
v=√T/μ
Where μ is mass per unit length.
v=λf
I plugged in the values for λ (wavelength) and f (frequency) to solve for velocity.
Then I symbolically solved the first equation for T:
T=v2

And BAM I got tension.
Hopes this helps anyone else with this same problem :-)
