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.
In what form does all radiant energy travel through space?
Radiant energy travels through space in the form of electromagnetic waves, specifically as photons. These photons have no mass and move at the speed of light.
Why heat and light energy called radiant energy?
Heat and light energy are called radiant energy because they travel in the form of electromagnetic waves that radiate outwards from a source. This form of energy can travel through empty space and does not require a medium to propagate, making it radiant.
Transfer of heat through open space?
The transfer of heat through open space without the use of any medium is called radiation. Radiant heat travels in electromagnetic waves and does not require a medium to carry it. Examples include the heat we feel from the sun or a fireplace.
What heat transfers through empty space by light waves?
Radiant heat is transferred through empty space by electromagnetic waves, specifically infrared radiation. These waves do not require a medium to propagate and can travel through the vacuum of space, allowing heat to be transferred from the Sun to Earth.
Why does radiant heat travel so quikly?
Travels at the speed of light.

In what form does radiant heat transmit?
Radiant heat transmits in the form of waves.
Describe what happens to radiant energy once it enters the atmosphere?
It may be converted into heat (or cause chemical reactions to occur), otherwise it remains radiant energy and escapes back into space. Note that much of what stays as heat is converted back into infra-red radiation and lost into space at night.

What is the definition of radiant energy for kids?
Radiant energy is energy that travels in waves and can move through empty space, like light from the sun. It is a form of energy that we can feel as heat or see as light.
What happens to most of the sun radiant energy?
Most of the Sun's radiant energy is absorbed by Earth's atmosphere and surface, where it is then converted into heat. Some of it is reflected back into space by clouds and the Earth's surface.
How does a radiant electric system heat a house?
A radiant electric system heats a house by using electric heating elements installed in the floors, walls, or ceiling to generate heat. These elements radiate heat directly to objects and people in the room, warming them up. The heat is emitted evenly and efficiently, providing a comfortable and consistent temperature throughout the space.
Is the sun an example of radiant energy?
Yes, the sun is a source of radiant energy.
