How does the frequency of radiant energy relate to the absolute temperature of the radiating source?

A low temp source emits low-frequency, long wavelength waves. A medium temp source emits medium frequency, medium wavelength waves. A high temp source emits high frequency, short wavelength waves.

∙ 14y agoThe wavelength of radiation is related to the frequency of radiation. Frequency is the rate of vibration of a wave source. High frequency vibrations produce short waves and low frequency vibrations cause longer waves. A low temp. source emits primarily low-frequency, long-wavelength waves. A high temp. does just the opposite.

What do radiant energy decreases or increases with?
The radiant energy increases as the frequency increase and the radiant energy decreases as the frequency decreases.
How do wavelengths of radiant energy vary with the temperature of the radiating source?
The answer to this is given by Wien's displacement law, at least for an ideal "black body" as the radiating source.The law states that the distribution of wavelengths has essentially the same shape at all temperatures (with the scale varying), with the peak wavelength λpeak occuring at:λpeak = b/T,where b is Wien's displacement constant and T is the absolute temperature.In S.I. units, b = 2.898×10−3 m·K to four significant figures (the unit is metre-Kelvin, not millikelvin).
What is mean radiant temperature?
The mean radiant temperature is the average effect of radiation from surrounding surfaces. At the center of the room this temperature can be taken as being equal to the mean surface temperature
What determines the amount of radiant energy that can be carried by an electro magnetic wave?
i believe the frequency
How does radiant heating system work?
There are many different ways to use radiant energy to heat your home including radiant flooring, radiant electric heating, radiant tiles... The site in the related links has tons of information on radiant heating. Technically, "radiant" heating is used to distinguish from "forced air" systems. In a radiant system the radiant elements emit heat and in an forced-air system the furnace heats air, which is then moved to where the heat is needed. A radiant system can be electrical, hyrdonic or steam-driven. For instance, a hydronic boiler heats water to about 180 degrees and uses circulators (forced hot water) to move the heated water to a finned-tube, floor-tubing, wall-tubing, or cast-iron radiator, heating the radiator, radiating heat into the room. The cooled water then flows back to the boiler to be heated again.
What are rules of incandescence?
the state of glowing while at a high temperature, caused by electrons in vibration atoms and molecules that are shaken in and out of their stable energy levels, emitting radiant energy in the process. The peak frequency of radiant energy is proportional to the absolute temperature of a heated substance
What is incandescence caused by?
the state of glowing while at a high temperature, caused by electrons in vibration atoms and molecules that are shaken in and out of their stable energy levels, emitting radiant energy in the process. The peak frequency of radiant energy is proportional to the absolute temperature of a heated substance
What is the meaning of incandescence?
the state of glowing while at a high temperature, caused by electrons in vibration atoms and molecules that are shaken in and out of their stable energy levels, emitting radiant energy in the process. The peak frequency of radiant energy is proportional to the absolute temperature of a heated substance
What do radiant energy decreases or increases with?
The radiant energy increases as the frequency increase and the radiant energy decreases as the frequency decreases.
What is the adjective for radiate?
The derivative adjective is radiant. The participles can also be used as adjectives: radiating and radiated.

What is the relationship between the wavelength and the frequency of radiant energy?
Wavelength and frequency are inversely proportional.

The mean radiant temperature is the average effect of radiation from surrounding surfaces. At the center of the room this temperature can be taken as being equal to the mean surface temperature
What are the four main factors that affect temperature?
* Air temperature * Humidity * Radiant Heat (direct heat radiating from an object such as an oven or even the sun) * Air Velocity
