Wave Vocabulary Flashcards
(29 cards)
Wave
a disturbance caused by a vibration; Waves travel away from the source that makes them
Medium
an agency or means of doing something.
Mechanical Wave
A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. While waves can move over long distances, the movement of the medium of transmission—the material—is limited. Therefore, oscillating material does not move far from its initial equilibrium position.
Transverse Wave
a wave vibrating at right angles to the direction of its propagation.
Longitudinal Wave
a wave vibrating in the direction of propagation.
Trough
a long, narrow open container for animals to eat or drink out of.
Amplitude
the maximum extent of a vibration or oscillation, measured from the position of equilibrium.
Crest
a comb or tuft of feathers, fur, or skin on the head of a bird or other animal.
synonyms:
Wave length
the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
Frequency
the rate at which something occurs or is repeated over a particular period of time or in a given sample.
Reflection
the throwing back by a body or surface of light, heat, or sound without absorbing it.
Refraction
the fact or phenomenon of light, radio waves, etc., being deflected in passing obliquely through the interface between one medium and another or through a medium of varying density.
Diffraction
the process by which a beam of light or other system of waves is spread out as a result of passing through a narrow aperture or across an edge, typically accompanied by interference between the wave forms produced.
Interference
the action of interfering or the process of being interfered with.
Electromagnetic Spectrum
the range of wavelengths or frequencies over which electromagnetic radiation extends.
Radiation
the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization.
Electromagnetic wave
Definition of electromagnetic wave. : one of the waves that are propagated by simultaneous periodic variations of electric and magnetic field intensity and that include radio waves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
Radio waves
an electromagnetic wave of a frequency between about 104 and 1011 or 1012 Hz, as used for long-distance communication.
Microwaves
an electromagnetic wave with a wavelength in the range 0.001–0.3 m, shorter than that of a normal radio wave but longer than those of infrared radiation. Microwaves are used in radar, in communications, and for heating in microwave ovens and in various industrial processes.
Infrared light
Infrared light is one type of light that is invisible to us. Gamma rays, X-rays, ultraviolet light, microwaves and radio waves are other types of invisible light. All of these rays and waves are the same type of electromagnetic energy.
Ultraviolet Light
Ultraviolet light is a form of radiation which is not visible to the human eye. It’s in an invisible part of the “electromagnetic spectrum”. Radiated energy, or radiation, is given off by many objects: a light bulb, a crackling fire, and stars are some examples of objects which emit radiation.
Gramma Rays
Part of the electromagnetic spectrum that consists of waves with the highest frequencies
Transmission
The passage of waves through a medium
Absorption
The disappearance of a wave into a medium the energy transferred by a wave is converted into another
