Wave and Electromagnetic Spectrum Flashcards

Front

Electromagnetic wave

Back

A form of energy that can move through the vacuum of space.

Front

Longitudinal (compressional) wave

Back

A wave that causes a medium to vibrate in a direction parallel to the direction in which the wave travels.

Front

Transverse wave

Back

A wave that moves the medium in a direction perpendicular to the direction in which the wave travels.

Front

Amplitude

Back

Height of a wave.

Front

Wavelength

Back

The distance between two corresponding parts of a wave.

Front

Rarefraction

Back

The part of a longitudinal wave where the particles of the medium are far apart.

Front

Compression

Back

The part of a longitudinal wave where the particles of the medium are close together.

Front

Period of a wave

Back

Time for one complete waveform to travel.

Front

Frequency

Back

The number of complete wavelengths that pass a point in a given time.

Front

Medium

Back

Material through which a wave travels.
