Science Vocabulary

Light Energy Light energy is a kind of kinetic energy with the ability to make types of light visible to human eyes.
Wavelength 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.
spectrum a band of colors, as seen in a rainbow, produced by separation of the components of light by their different degrees of refraction according to wavelength.
earthquake a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action.
vacuum a space entirely devoid of matter.
Tectonic plate A tectonic plate (also called lithosphere plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere.
vocal relating to the human voice.
sound vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear.
electromagnetic spectrum the range of wavelengths or frequencies over which electromagnetic radiation extends.
sound wave a wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air.
radiant energy Radiant energy is energy that travels by waves or particles, particularly electromagnetic radiation such as heat or x-rays.
radiation the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.
vibration an instance of vibrating.
seismic relating to earthquakes or other vibrations of the earth and its crust.
amplitude the maximum extent of a vibration or oscillation, measured from the position of equilibrium.
longitudinal wave a wave vibrating in the direction of propagation.
Transverse wave a wave vibrating at right angles to the direction of its propagation.
detect discover or identify the presence or existence of.
ultraviolet (of electromagnetic radiation) having a wavelength shorter than that of the violet end of the visible spectrum but longer than that of X-rays.
infrared (of electromagnetic radiation) having a wavelength just greater than that of the red end of the visible light spectrum but less than that of microwaves.
tough (of a substance or object) strong enough to withstand adverse conditions or rough or careless handling.
tough 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.
reflection the throwing back by a body or surface of light, heat, or sound without absorbing it.
wave move one's hand to and fro in greeting or as a signal.
