conduction: is the heat transfer through touch
What is heat?
Heat is energy flowing through the air.
What is Conduction?
Conduction is the transfer of heat between objects or substances
that are in direct contact with each other. Example: Someone
touching a hot pot.
What is Convection?
Convection is the transfer of heat by movement through a
medium, liquid or air. Example: Hot air at the top of your house,
and cold air at the bottom of your house.
What is Radiation?
Radiation is the transfer of energy along electromagnetic waves,
like light waves or radio waves. Example: Electromagnetic waves
warming up your house.
Light
absorb
angle of incidence: The angle of light hitting something
angle of reflection: A light beam reflecting off a mirror
concave: Objects that make light bend inwards
convex: Objects that make light bend outwards
diffuse: To spread across
light: Something that makes things visible
light spectrum: Is the range of all possible frequencies of electromagnetic radiation
light waves: Something a human eye can see
opaque: lets no light pass through
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.
transmitting: to pass from one place to another
translucent: Lets some light pass through
transparent: Lets all light through
white light: all the wavelengths of the visible spectrum at equal intensity.
Heat Vocab
conduction: is the direct heat transfer through touch
conductor: a material or device that conducts or transmits heat
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: Radiation is energy that comes from a source and travels through some material or through space.
thermal energy: Thermal energy is generated and measured by heat of any kind
thermal expansion: Thermal expansion is the tendency of matter to change in volume in response to a change in temperature.
thermometer: a thing that measures heat
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.
