waves
(14 decks)
Wave- is a rhythmic disturbance that carries energy through matter and space.; carries energy from one place to another. Waves are a form of energy.
Wavelength- distance of a “repeating unit”, also called a cycle; measures how long a wave is
Amplitude- measures DISPLACEMENT (height of a wave) size of the disturbance; distance between “rest & crest” or “rest & trough”
Trough- bottom, or lowest point of a wave
Crest- “peak” or top of a wave
Speed- how fast the wave travels (velocity); measured by multiplying the wavelength by the wave frequency, v = w x f
Frequency- How often number of wavelengths that pass any point per second number of wavelength
Medium- matter such as solid, liquid, or gas and is what a wave is carried by; ex/ ocean waves move through water \
Electromagnetic wave- the energy moves through disturbances in the electromagnetic field. Does not require a medium to travel through; energy is transferred by way of radiation.
Mechanical wave- the energy is transferred by vibrations of medium. Three types of mechanical waves: transverse, longitudinal, and surface waves
Transverse wave- Vibration is perpendicular to the direction of the motion of the wave, the vibration is at 90 degrees (right angles) to the wave pulse
Longitudinal (compression) wave- Vibration is in the same direction (parallel) as wave pulse (parallel to wave pulse)
Surface wave- Vibration is circular Ex/ Ocean waves; ground surface waves
Matter/Elements
