Sinusoidal Oscillator Quick Question

Click For Summary
SUMMARY

The discussion focuses on calculating the velocity required to establish a standing wave with 5 segments on a string driven by a sinusoidal oscillator at a frequency of 100 Hz. The relevant equation for standing waves, fn = nV/2L, is identified, where fn is the frequency, n is the number of segments, V is the wave velocity, and L is the length of the string. It is concluded that additional information, specifically the total length of the string, is necessary to determine the velocity accurately.

PREREQUISITES
  • Understanding of standing wave principles
  • Familiarity with wave frequency and velocity equations
  • Knowledge of sinusoidal oscillators
  • Basic concepts of wave mechanics
NEXT STEPS
  • Research the relationship between frequency, wavelength, and wave velocity
  • Study the characteristics of standing waves in strings and pipes
  • Learn about boundary conditions for waves on strings
  • Explore the impact of string length on wave formation
USEFUL FOR

Students studying physics, particularly those focusing on wave mechanics, as well as educators looking for examples of standing wave phenomena in strings and oscillatory systems.

Homework Statement


Drive one end of the string with sinusoidal oscillator of frequency 100hz. What velocity is required to setup a standing wave with 5 segments?


Homework Equations


I know for standing wave that fn = nV/2L and you can isolate out velocity variable.


The Attempt at a Solution



Though I'm not very familiar if the string is not tied down at both ends and I was wondering if someone could explain how to obtain the velocity from the 2 givens.

You don't have enough information. You also need the total length of the string.

The standing wave in a string fixed at one end and free at the other end will look the same as in a pipe closed at one end and open at the other end.
