Lesson Plan: Drawing Graphs of Periodic Motion
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to use graphs to represent the amplitudes, periods, frequencies, and wavelengths of oscillations.
Objectives
Students will be able to
- recall that oscillations can be represented using waveforms,
- recall that the term amplitude refers to the magnitude of the maximum displacement of an oscillating system,
- identify the amplitude of an oscillation on a diagram of the waveform,
- identify the period of an oscillation on a diagram of the waveform,
- recognize that a complete oscillation is oscillatory motion that continues for a time equal to the period of the oscillation,
- recall that there is an inverse relation between frequency and period,
- identify waveforms of given periods and amplitudes,
- recall what is meant by the term wavelength,
- determine the wavelength of a wave from a diagram of a transverse waveform,
- recall that wavelengths are measured in units of length,
- recognize that a longitudinal wave can be represented using a transverse waveform.
Prerequisites
Students should already be familiar with
- the definition of oscillatory motion.
Exclusions
Students will not cover
- propagation of waves,
- calculation of period from frequency, or vice versa,
- types of waves.
