Waves note Flashcards
Wave
The transport of energy without the transport of matter
longitudinal waves
- Shakes the ground back and forth in the same direction and opposite direction.
-They move fast
-sound 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 = higher energy
Frequency
Number of wave 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, Violet
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.
