What are two objects on Earth that are sources of radiant energy?

What are two objects that are sources of radiant energy?

Some examples of radiant energy include:

  • The heat emitted from a campfire.
  • Emission of heat from a hot sidewalk.
  • X-rays give off radiant energy.
  • Microwaves utilize radiant energy.
  • Space heaters produce radiant energy.
  • Heat created by the body can be radiant energy.
  • Home heating units.
  • Fixtures that convert solar energy to heat.

What are the sources of radiant energy?

Radiant energy sources include the entire electromagnetic radiation spectrum, including gamma rays, x-rays, radio frequencies, microwaves, light and heat. Often, radiant energy is used to describe the type of particle in question, but it is actually the energy carried by the particle.

What are the 7 types of radiant energy?

There are seven natural forms of EMR. Gamma rays have the highest energy and shortest wavelength. Then come X-rays, ultraviolet light, visible light, infrared radiation and microwave radiation. Finally, radio waves have the lowest energy and longest wavelength.

What is the source of radiant energy of the sun?

The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun’s core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. During the fusion process, radiant energy is released.

What is the main source of thermal and radiant energy?

Thermal radiation is generated when heat from the movement of charges in the material (electrons and protons in common forms of matter) is converted to electromagnetic radiation. Sunshine, or solar radiation, is thermal radiation from the extremely hot gasses of the sun, and this radiation heats the earth.

How is radiant energy used on Earth?

Radiant energy is used for radiant heating. It can be generated electrically by infrared lamps, or can be absorbed from sunlight and used to heat water. The heat energy is emitted from a warm element (floor, wall, overhead panel) and warms people and other objects in rooms rather than directly heating the air.

How does radiant energy reach the Earth?

Energy is transferred from the sun to Earth via electromagnetic waves, or radiation. Most of the energy that passes through the upper atmosphere and reaches Earth’s surface is in two forms, visible and infrared light. … This transfer of energy can take place by three processes: radiation, conduction, and convection.
