Radiant energy includes visible light, x-rays, gamma rays, and radio waves. Radiant energy is electromagnetic energy that travels in transverse waves. Kinetic energy is the motion of waves, electrons, atoms, molecules, substances, and objects. Hydropower is another example of gravitational energy, where gravity forces water down through a hydroelectric turbine to produce electricity. When a person rides a bicycle down a steep hill and picks up speed, the gravitational energy is converting to motion energy. The higher and heavier the object, the more gravitational energy is stored. Gravitational energy is energy stored in an object's height. Large amounts of energy can be released when the nuclei are combined or split apart. Nuclear energy is energy stored in the nucleus of an atom-the energy that holds the nucleus together. Compressed springs and stretched rubber bands are examples of stored mechanical energy. Mechanical energy is energy stored in objects by tension. For example, chemical energy is converted to thermal energy when people burn wood in a fireplace or burn gasoline in a car's engine. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy. The microwave oven works with the concept of radiant energy (electromagnetic waves).Potential energy is stored energy and the energy of position.Ĭhemical energy is energy stored in the bonds of atoms and molecules. For example, when micro-waves (which forms part of the entire spectrum) are set-off in a microwave oven, the water molecules in the food are charged and caused to vibrate billions of times per second, generating heat that causes the food to cook. When radiant energy comes into contact with matter, it changes the properties of that matter. In the illustration above, you will see the different radiant energy levels represented by their wavelengths. 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. Radiant energy is the energy of electromagnetic waves.
