Frequency- How often number of wavelengths that pass any point per second number of wavelength Flashcards

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
