Waves Flashcards
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-need medium or materiel to pass through.
S waves / transverse waves
-Secondary wave-moves slowly up and down.- Light waves
Amplitude
-Measure the height of the wave from the crest (high point) or through (low point) of the midline
higher amplitude= high energy
Wavelength
Measure the horizontal distance between cycles
Crest to crest
Shorter wavelength
Frequency
Number of waves cycle 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, Violet (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 or 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.
