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
