Lesson Plan: Resonance of Strings
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to determine the resonant oscillation frequency of a taut string and describe its harmonic oscillation modes.
Objectives
Students will be able to
- recognize that a standing wave on a string is produced by waves of the same frequency traveling along the string in opposite directions,
- recognize that the phase of a wave on a string changes by radians when the wave reflects from a fixed end of the string,
- recognize that the number of harmonic oscillation modes, , of a standing wave of wavelength on a string of length is described by the equation ,
- apply the equation to waves that interfere to produce a standing wave.
Prerequisites
Students should already be familiar with
- .
Exclusions
Students will not cover
- the dispersion of waves.
