Waves

Amplitude

the height of a wave's crest

Frequency

the number of complete wavelengths that pass a point in a given time

Wavelength

Distance between each crest

Wave

a disturbance that transfers energy from one place to another but doesn't transfer energy

Crest

the highest point of a transverse wave

Trough

the lowest point of a transverse wave

medium

Material through which a wave travels

resting point

The horizontal line through the middle of the wave

transverse wave

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

mechanical wave

a wave that can travel only through matter

Absorption

is the transfer of energy by a wave to the medium through which it travels

Transmission

is the passage of light through an object

Reflection

bouncing of a wave off a surface

opaque

not letting light through; not clear or lucid; dense, stupid

Transluscent

A material that is only partially clear; that allows some light to enter. Example: frosted glass

Transparent

allowing light to pass through; easily recognized or understood; easily seen through or detected
