The Electromagnetic Spectrum. 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.
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.
An oscilloscope is a useful tool for anyone working with electrical signals because it provides a visual representation of the signal's shape, or waveform. This allows you to measure properties of the wave, such as amplitude or frequency. The initial signal above is a 200Hz sine wave, which has an amplitude of 5 volts.
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.
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.
Amplitude is generally calculated by looking on a graph of a wave and measuring the height of the wave from the resting position. The amplitude is a measure of the strength or intensity of the wave. For example, when looking at a sound wave, the amplitude will measure the loudness of the sound.
