Heat is thermal energy that is transferred in three different ways: Conduction, Convection, and Radiation. Conduction: a material or devise that conducts or transmits heat, electricity, or sound, esp. when regarded in terms of its capacity to do this. Convection: heat transfer in a gas or liquid by the circulation to perform work. Radiation: the emission of energy as electromagnetic waves or as moving subatomic particles.

CONVECTION
HEAT
conduction: the process by which heat is directly transmitted through touching
conductor: a material or device that conducts or transmits heat, electricity, or sound, esp.
convection: Heat transfer in a gas or liquid by the circulation of currents from one region to another.
energy: the property of matter and radiation that is manifest as a capacity to perform work
insulator: a substance that does not readily allow the passage of heat or sound.
medium: the intervening substance through which impressions are conveyed to the senses or a force acts on objects at a distance.
radiation: the emission of energy as electromagnetic waves or as moving subatomic particles
thermal energy: Thermal energy is generated and measured by heat of any kind. It is caused by the increased activity or velocity of molecules in a substance, which in turn causes temperature to rise accordingly.
thermal expansion: Thermal expansion is the tendency of matter to change in volume in response to a change in temperature.
thermometer: an instrument for measuring and indicating temperature

LIGHT
absorb: take in or soak up (energy, or a liquid or other substance)
angle of incidence: the angle that an incident line or ray makes perpendicular to the surface at the point of incidence.
angle of reflection: the angle made by a reflected ray with a perpendicular to the reflecting surface
concave: having an outline or surface that curves inward like the interior of a circle or sphere.
convex: having an outline or surface curved like the exterior of a circle or sphere.
diffuse: spread or cause to spread over a wide area
light: the natural agent that stimulates sight and makes things visible.
light spectrum: The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation.
light waves: visible light is electromagnetic radiation that is visible to the human eye, and is responsible for the sense of sight
opaque: not able to be seen through; not transparent.
prism: a solid geometric figure whose two end faces are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms.
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
roy g biv: Roy G. Biv is an acronym for the sequence of hues commonly described as making up a rainbow: Red, Orange, Yellow, Green, Blue, Indigo and Violet.
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.
translucent: a substance that allows light, but not detailed images, to pass through; semitransparent.
transmitted: to pass from one place to another
transparent: (of a material or article) allowing light to pass through so that objects behind can be distinctly seen.
white light:all the wavelengths of the visible spectrum at equal intensity.

SOUND
amplitude (volume): the maximum extent of a vibration or oscillation, measured from the position of equilibrium.
frequency (pitch): the rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light)
sound wave: a wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air.
speed of sound: The speed of sound is the distance traveled during a unit of time In dry air at 20 °C, the speed of sound is 343.2 meters per second.
subsonic: relating to or flying at a speed or speeds less than that of sound.
supersonic: involving or denoting a speed greater than that of sound.
wavelengths: the distance between successive crests of a wave, esp. points in a sound wave or electromagnetic wave.
