the black body radiation curve for different temperatures peaks at a wavelength inversely proportional to the temperature.
the rate at which something occurs or is repeated over a particular period of time or in a given sample.
e lowest temperature that is theoretically possible, at which the motion of particles that constitutes heat would be minimal. It is zero on the Kelvin scale
the total radiant heat energy emitted from a surface is proportional to the fourth power of its absolute temperature.
an emission spectrum that consists of a continuum of wavelengths.
The distance between one peak or crest of a wave and the next peak or crest. It is equal to the speed of the wave divided by its frequency, and to the speed of a wave times its period.
the natural agent that stimulates sight and makes things visible.
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.
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.
6.62607004 × 10-34 m2 kg / s
the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
an increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other. The effect causes the sudden change in pitch noticeable in a passing siren, as well as the redshift seen by astronomers.
the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.
the branch of science concerned with the investigation and measurement of spectra produced when matter interacts with or emits electromagnetic radiation.
of or denoting a scale of temperature on which water freezes at 32° and boils at 212° under standard conditions.
