WAVE TERMINOLOGY
AMPLITUDE
The maximum displacement point on a wave away from its undisturbed postition (the highest or lowest point)
-
-
-
-
-
TYPES OF WAVES
TRANSVERSE
This is when the oscillations in the wave are perpendicular to the direction the wave travels( imagine how a water wave looks)
-
-
Top of the wave is called a crest, and the bottom is a trough
LONGITUDINAL
-
-
-
The extended part is a rarefaction, the compressed part is a compression
-
ELECTROMAGNETIC SPECTRUM
-
-
USES
-
-
-
-
Ultraviolet- energy efficient lamps, sun tanning
