Waves And Electromagnetic Flashcards
Wave
The transfer of energy without transferring matter
Crest
The highest point or peak of a wave.
Trough
The lowest point or valley of a wave
Amplitude
The distance from the resting point to the crest of a wave
wavelength
the distance from crest to crest or trough to trough in a wave is called
Wave frequency
The number of waves that pass a given point in a set period of time.
Time period
Time for a complete cycle to pass a given point
mechanical wave
Matter through which a mechanical wave travels
transverse wave
A wave in which the energy travels perpendicular to the direction of the disturbance
electromagnetic waves
A wave that does not need a medium to travel through
particles vibrate
A wave in which the energy travels in the same direction as the disturbance.
longitudinal wave
The point in a longitudinal wave where the matter is pushed closer together
rarefaction
The point in a longitudinal wave where the matter is spaced farther apart
Refraction
When waves strike a surface and bounce back in another direction.
obstacles
The bending of waves as they pass through a material
