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).

The reason the Sun's radiant energy is of shorter wavelengths than the Earth's is because the Sun?
The Sun is hotter.
What is Radiant light energy?
This is part of the Electromagnetic radiation spectrum, visible light occupies a small part of this spectrum, but all wavelengths have the same physical properties
What is the difference Between Light energy and Radiant Energy?
Light is light. Radiant is Radiant.
Is radiant energy sustainable?
Radiant energy is sustainable because we can handle it ex.we can handle the light from radiant energy.
The pupil of your eye is a net absorber of radiant energy a net emitter of radiant energy neither a net absorber or emitter of radiant energy?
A net absorber of radiant energy.
How is radiation work with popcorn?
by the radiating the process of emitting radiant energy in form of particles or waves
The reason the Sun's radiant energy is of shorter wavelengths than the Earth's is because the Sun?
The Sun is hotter.
Is there a relationship between radiant energy and electrical energy?
there is a relationship they produce temperature.
How do chloroplastids differ from chromoplastids?
Chloroplastids are meant to capture solar energy for photosynthesis whereas chromoplastids provide various types of pigmentation to the plant parts radiating energy rich wavelengths of sunlight.
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 does radiant heating do that saves energy?
Radiant heat is an excellent way to save energy. The heating system lays beneath your floor and the heat radiates up. It is more energy efficient in that there is more area radiating heat than other heating otions and thus quicker heat returns. This causes your heating system to run less and save you money and energy.
What is Radiant light energy?
This is part of the Electromagnetic radiation spectrum, visible light occupies a small part of this spectrum, but all wavelengths have the same physical properties
Light waves striking an object can cause it to increase its temperature from this you can infer that?
From this you can infer that energy has been transferred by radiant energy.
What is the difference Between Light energy and Radiant Energy?
Light is light. Radiant is Radiant.
Is radiant energy sustainable?
Radiant energy is sustainable because we can handle it ex.we can handle the light from radiant energy.
Is Radiant Energy a renewable energy source?
Radiant energy is energy in the form of electromagnetic energy with a range of wavelengths that extends from radio waves to gamma rays. This includes heat (infrared radiation) and light. It is a derived energy (produced by something) rather than a source of energy - nobody has found a deposit of radiant energy. It is created by a number of processes including:nuclear fission and fusionchemical transformations including fuel burningfrictionelectricity including lightningas a consequence some of the energy sources are renewable, others are not and some are essentially inexhaustible.
