Longitudinal (compression) wave:
|
A wave in which the vibration of the medium is parallel to the direction the wave travels
|
|
Amplitude:
|
The maximum displacement of a medium from the rest position.
|
|
Rarefaction:
|
An area of longitudinal wave where the particles of the medium are spread out.
|
|
Compression:
|
An area of the longitudinal wave where the particles of the medium are close together.
|
|
Period:
|
The time required for one complete cycle of a periodic motion.
|
|
Frequency:
|
The number of complete cycles per unit time for a periodic motion.
|
|
Wave Velocity:
|
The rate at which a wave travels through a medium.
|
|
Wavelength:
|
The distance between a point on a wave and the same point on the next cycle of the wave.
|
|
Transverse Wave:
|
A wave that causes a medium to vibrate at right angles to the direction in which the wave travels.
|
|
Mechanical Wave:
|
A disturbance in matter that carries energy from one place to another.
|
|
Electromagnetic wave:
|
A transverse wave consisting of changing electric and changing magnetic fields.
|
|
Surface Wave:
|
A wave that travels along a surface separating the two media.
|
|
Medium:
|
The material through which a wave travels.
|
|
Reflection:
|
The interaction that occurs when a wave bounces off a surface that it cannot pass through.
|
|
Refraction:
|
The bending of a wave as it enters a new medium at an angle.
|
|
Wave interference:
|
The variation of wave amplitude that occurs when waves of the same or nearly the same frequency come together.
|
|
Constructive interference:
|
The interference among two or more waves in which displacements combine to produce a wave with a larger displacement.
|
|
Destructive Interference:
|
The interaction among two or more waves in which displacement combine to produce a wave with a smaller displacement.
|
|
Diffraction:
|
The bending of a wave as it moves around an obstacle or passes through a narrow opening.
