Waves - Unit 1 Vocab

Front

Transverse Wave

Back

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

Front

Longitudinal Wave

Back

a wave in which the particles of the medium move parallel to the direction of energy of the wave travels

Front

Crest

Back

Highest point of a wave

Front

Trough

Back

Lowest point of a wave

Front

Wavelength

Back

The distance between two matching parts of a wave (crest to crest) (trough to trough)

Distance between waves

Front

Frequency

Back

The number of complete waves that pass a given point in a certain amount of time

How many waves?

Front

Energy vs amplitude

Back

More amplitude (higher wave) = more energy

Low amplitude (shorter wave) = less energy

Front

Energy

Back

Waves transfer ENERGY NOT PARTICLES

Front

Frequency vs. Wavelength

Back

as frequency increases, wavelength decreases

Higher frequency = lower wavelength

More waves = less space between waves

Front

Compression

Back

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