Waves ~ Properties

Just like wave particles, dominoes transfer energy from one to the next, without any one domino having to move the whole distance across the table.

Motion of waves moves energy from one place to another.

Waves are distinct from other energy transport systems because they can transport energy without the need to transport matter. 

electromagnetic waves or light waves transfer energy, they travel through space and do not need a medium. 

Mechanical waves transfer energy through a medium.

transverse~ Seismic S Waves. Rope waves

longitudinal waves~ Sounds Waves, spring waves

The highest point a wave reaches above equilibrium (midline) is its crest and the lowest point a wave reaches below equilibrium is its trough.

Waves are measured by their amplitude, wavelength, and frequency.

amplitude equals half the vertical distance from crest to trough. 

In sound waves, amplitude corresponds to loudness; as the wave amplitude increases, so does the loudness of the sound and the energy.

The waves with the most amplitude are the loudest and have the most energy.

Wavelength determines which waves we can sense.

Humans can hear sound waves with wavelengths between about 0.02 m (high pitches) and 20 m (low pitches). 

Frequency is a measure of the number of times a wave cycles per unit of time (typically 1 second). 

Frequency is also defined as the number of waves that pass a certain point in 1 second. Waves with higher frequencies have more energy.
