Image Credit: NASA. The electromagnetic spectrum is comprised of all frequencies of electromagnetic radiation that propagate energy and travel through space in the form of waves. Longer wavelengths with lower frequencies make up the radio spectrum.
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. Figure 2: Properties of a wave. (Credit: Pearson Prentice Hall)
1. Draw a picture of a wave and label wavelength and amplitude. What is a wave? A wave is simply energy moving from one place to another. It always needs something to move through. Example: Sound is the wave and the air is the medium. Wave Anatomy. Crest. Wavelength = : : ( ) Trough. In Phase. Amplitude. = : : ( ) Period.
The amplitude of a wave is a measure of the displacement of the wave from its rest position. The amplitude is shown on the graph below. Amplitude is generally calculated by looking on a graph of a wave and measuring the height of the wave from the resting position.
A wave’s amplitude is the maximum distance (positive or negative) a wave reaches from its rest position. Wavelength is the distance between the same spot on two sections of a wave. A wave’s frequency can be measured by how many crests (or how many troughs) pass a location in a certain amount of time.
