Waves
The transport of energy WITHOUT the transport of matter.
P waves/ longitudinal waves
Shakes the ground back and forth in the same direction and opposite direction. They move fast. Sound waves. Needs a MEDIUM or material to pass through.
S waves/ transverse waves
Secondary wave. Moves slowly up and down.Light waves.
Amplitude
Measures the height of the wave from the crest (high point) or trough (low point) of the wave to the midline. *Higher amplitude = higher energy.
Wavelength
Measures the horizontal distance between cycles. *Crest to Crest. *Shorter wavelength = shorter higher energy
Frequency
Number of waves cycles that are completed in one second. *Higher frequency = higher energy.
Electromagnetic Spectrum
Light waves with different energies, wavelengths, and frequencies.
Visible Light Waves
Light that humans can see: Red, Orange, Yellow, Green, Blue, Indigo, Violent (ROY G BIV)
Transmission
The passing of waves through or into a medium.
Reflection
The bouncing back of a wave after it strikes a barrier of object.
Absorption
The process of taking in or soaking up energy carried by a light wave.
Refraction
The bending of a wave when it strikes a medium at an angle.
