Anatomy of a Wave Worksheet. Objective: Identify the parts of a wave and draw your own diagrams of waves. Background: Many types of waves exist, including electromagnetic waves and mechanical waves. Waves move in different ways and have different properties.
A wave (Figure 2) is a periodic perturbation from an undisturbed or rest state that is transmitted in space. The maximum deviation from this undisturbed state is called the amplitude of the wave, and is a measure of the intensity of the perturbation; the top of the wave is called a crest and the lowest state, a trough.
The frequencies shown in the following two diagrams are within range of those generated by common sources and observable using common detectors. Ranges such as microwaves, infrared, etc., overlap. They are categorized in spectrum charts by the artificial techniques we use to produce them.
Electro-magnet-ic radiation with short wavelengths contains a great amount of energy. Scientists name the different regions of the elec-tromagnetic spectrum according to their wave-lengths. (See figure 1.) Radio waves have the longest wavelengths, ranging from a few centime-ters from crest to crest to thousands of kilometers.
