A traveling disturbance that carries energy from one place to another
Wave
Highest point (peaks) of wave
Crest
Lowest point of wave
Trough
The greatest movement from rest. Found by measuring the distance from crest to crest or trough to trough
Amplitude
The distance between 2 consecutive crests or troughs.
Wavelength
Compression, rarefraction, amplitude
Wave
The number of waves passing a point in a certain amount of time. Measured in hertz (Hz).
Frequency
(Longitudinal /compressional, transverse, surface) waves that require a medium to travel through
Mechanical Waves
Vibrates up and down or right to left. The motion of the medium is at right angles to the direction of the wave.
Transverse Waves
Move in a circular motion. They're a combination of waves that move both ways.
Suface Waves
Empty space- the absence of matter
Vacuum
The bending of waves due to a change in speed
Refraction
When a wave strikes a barrier and strikes back
Reflection
_______ is the disturbance that travels through a medium as a longitudinal wave.
Sound Waves
Waves get _______ into the material; amplitude gets smaller and smaller.
Absorption
The bending of waves around barriers or through an opening of a barrier.
Diffraction
When 2 or more waves arrive at the same time and combine into one.
Interference
_________ are transverse waves which only electromagnetic waves that are visible to the human eye
Light Waves
The matter through which a mechanical wave travels through.
Medium
Move in and out as a series of compressions or rarefractions. The motion of the medium is parallel to the direction of the wave.
Longitudinal Waves
Light waves that don't require a medium to travel through. They travel through a vacuum.
Electromagnetic Waves
The _______ is made up of transverse waves from gamma rays to radio waves. It's organized from the shortest to longest wavelength.
