Heat transfer through radiation takes place in form of electromagnetic waves mainly in the infrared region. Radiation emitted by a body is a consequence of thermal agitation of its composing molecules. Radiation heat transfer can be described by a reference to the so-called 'black body'.
A black body is defined as a body that absorbs all radiation that falls on its surface. Actual black bodies don't exist in nature - though its characteristics are approximated by a hole in a box filled with highly absorptive material. The emission spectrum of such a black body was first fully described by Max Planck.
A black body is a hypothetic body that completely absorbs all wavelengths of thermal radiation incident on it. Such bodies do not reflect light, and therefore appear black if their temperatures are low enough so as not to be self-luminous. All blackbodies heated to a given temperature emit thermal radiation.
What else can I help you with?
Heat Travels from the sun to the earth by means of a process called?
Heat travels from the sun to the Earth through a process called radiation. Radiation is the transfer of heat energy through electromagnetic waves such as light.
What is the process by which the heat moved What is the process by which the heat moved from the asphalt to the person calledfrom the asphalt to the person called?
radiation
Heat being transferred from the sun to earth is an example of which process convection expansion radiation or conduction?
Radiation. Heat from the sun is transferred to Earth through electromagnetic radiation in the form of sunlight.
How are conduction and radiation?
They both are the way or the process to transfer heat.
In which process of transfer of heat in which material medium is not required?
Radiation is the process of heat transfer where material medium is not required. Energy is transferred through electromagnetic waves such as infrared radiation or light. This process can occur in a vacuum as well.
At a fast-food restaurant through what process is heat transferred between a heat lamp and hamburgers?
Heat is transferred from the heat lamp to the hamburgers through radiation. The heat lamp emits infrared radiation, which is absorbed by the surface of the hamburgers, warming them up.
What is the energy transfer process that does not require the presence of molecules to transfer heat?
Radiation is the energy transfer process that does not require the presence of molecules to transfer heat. It can occur through empty space and does not require a medium to carry the heat. Examples include heat transfer from the sun to the Earth and infrared radiation emitted by objects.
What form of heat transfer is caused by the greenhouse effect?
There are three types of heat transfers: conduction, convection and radiation. The heat transfer caused by the greenhouse effect is radiation.
How is heat trans fered from the sun to the earth?
Through the process of radiation.
A substance can absorb heat energy by the process of?
There are three methods by which substances absorb heat. These are conduction, or heat transfer through contact, convection, or heat transfer through fluid motion, and radiation, or heat transfer through electromagnetic radiation.
What actually happen during heat radiation process?
In the heat radiation process heat radiates. I'm sorry, you'll need to be more specific, since I really can't think of how to put it in much simpler terms than it already is.
What form of electromagnetic energy can transfer heat through radiation?
Infrared radiation is a form of electromagnetic energy that can transfer heat through radiation. It works by emitting and absorbing infrared radiation between objects without direct contact, transferring heat in the process.
