White light, for example, is a form of radiant energy, and its frequency forms a tiny bit of the entire electromagnetic spectrum. The shorter the wavelength, the higher its frequency, and vice versa. The entire wave system from the lowest frequency to the highest frequency is known as the electromagnetic spectrum. There are different kinds of electromagnetic waves, and all of them have different wavelengths, properties, frequencies, and power, and all interact with matter differently. The energy in the electromagnetic waves is what we call radiant energy. These waves resemble the ripple (mechanical) waves you see when you drop a rock into a swimming pool, but with electromagnetic waves, you do not see them, but you often can see the effect of it. Now, the electrical field induced causes waves, called electromagnetic waves, and they can travel through a vacuum (air), particles or solids. That is possible by electromagnetic waves.īefore we go any further, let us understand what electromagnetic waves are.Įach time static energy from electric and magnetic force comes together, they induce an electric field around them.Īn example of an electric static force is the shock you get when you hold a metal doorknob.Īn example of a magnetic force is the pull that attracts metals to the magnet.
The sun’s heat is not transmitted through any solid medium but a vacuum. For example, we receive the heat from the sun, which is located very far from the earth via radiation. It is a form of energy that can travel through space. Other scientists call it "energy from the vacuum".Radiant energy is the energy of electromagnetic waves. It may come from the earth or it may come from the atmosphere. This type of wave apparently is not visible to you and is available everywhere. Radiant energy on the other hand harnesses its power from electromagnetic waves. When the wind blows it rotates the blade thus generating electricity.
In the case of wind power generation, a tower is erected on a piece a piece of land and a wind turbine is installed on top of the tower. These solar panels are normally installed on the roof where it can be have the maximum exposure to sunlight.
Solar power is generated by collecting sunlight through a solar cell panel and is converted into electricity. Radiant energy has several advantages over a solar and a wind power generator. He is the man who built the Niagara Falls hydro-electric plant, the first in the world. Nicola Tesla is the inventor of alternating current generator and has over 700 patents under his name. This principle was first introduce by Nicola Tesla more than 100 years ago.
