TermDefinition
Wave a repeating disturbance or movement that transfers energy through matter or space.
Medium matter the wave travels.
Transverse waves matter in the medium moves back and forth at right angles to the direction that the wave travels.
Compressional waves matter in the medium moves back and forth along the same direction that the wave travels.
Crests the highest points on a transverse wave.
Troughs the lowest points on a transverse wave.
Rare fraction less-dense region of a compressional wave.
Wave length distance between one point on a wave and the nearest point just like it.
Frequency the number of wavelengths that pass a fixed point each second.
Period amount of a time it takes one wavelength to pass a point.
Amplitude related to the energy carried by a wave.
Refraction bending of a wave caused by a change in its speed as it moves from one medium to another.
Diffraction occurs when an object causes a wave to change direction and bend around it.
Interference two or more waves overlap and combine to form a new wave.
Standing wave special type of wave pattern that forms when waves equal in wavelength and amplitude, but traveling in opposite directions, continuously interfere with each other.
Resonance process by which an object is made to vibrate by absorbing energy at its natural frequencies.
