Radiant heat is when thermal energy is converted to electromagnetic energy. The movement of atoms and molecules generates electric and magnetic fields. Photons are emitted and carry (transfer) the energy. This is called thermal radiation.
A less strict meaning is the heating of objects, like walls , floors etc., to transfer heat into an area.
What else can I help you with?
What is the difference between convection and radiant heat?
Convection heat is the transfer of heat through the movement of fluids, like air or water, while radiant heat is the transfer of heat through electromagnetic waves, like from the sun or a fire.
Which method of heat transfer is the most important in a structure fire?
In a structure fire, convection is the most important method of heat transfer. Convection is the transfer of heat through the movement of fluids like air or gases. In a structure fire, hot air and gases rise, carrying heat with them and spreading the fire to other parts of the structure.
What is the difference between radiant heat and convection heat?
In convection heat you heat the air first and then use the hot air to heat yourself. In radiant heat, the energy must be radiated directly from the heat element to your body. Note that radiant is much more directional.
What heat transfer is when you feel warm glow of a bonfire?
The heat transfer you feel from a bonfire is primarily radiant heat transfer. This is when heat energy is transferred through electromagnetic waves from the hot flames to your body, causing you to feel warm.
What process provided the radiant heat?
Radiant heat is provided through electromagnetic waves that travel directly from a heat source to an object. This type of heat transfer does not require a medium like air or water, making it an efficient and direct way to warm objects.
How many heat transfer zone in boiler?

What energy is radiation?
Transfer of heat though waves.
How does radiant waves transfer heat energy?
By exciting the atoms in the matter. Pr. definition, heat is the jiggling of atoms, the radiant energy is shaking the atoms, by doing this the heat is transferred and absorbed.
What heat transfer is when you feel warm glow of a bonfire?
The heat transfer you feel from a bonfire is primarily radiant heat transfer. This is when heat energy is transferred through electromagnetic waves from the hot flames to your body, causing you to feel warm.
Heat can be transferred without the requiement of a solid liquid or gaseous medium what is the name given to this form of heat transfer?
Radiant heat or Radiation
What exactly is radiant energy?
the process by which heat is transfer from one body to another {in air} while using no medium is known as radiation or radiant energy.
What process provided the radiant heat?
Radiant heat is provided through electromagnetic waves that travel directly from a heat source to an object. This type of heat transfer does not require a medium like air or water, making it an efficient and direct way to warm objects.
What are the differences between radiant and infrared heat?
Radiant heat is a form of heat transfer that travels in waves and can be felt directly on the skin, while infrared heat is a type of electromagnetic radiation that is invisible to the human eye and is often used for heating objects or spaces.
The warmth you feel when standing beneath a heat lamp is an example of what?
The warmth you feel when standing beneath a heat lamp is an example of radiant heat transfer. The heat lamp emits infrared radiation, which travels in waves and is absorbed by your body, resulting in the sensation of warmth.
