In atomic bombs and in the fission reactors of nuclear power plants, uranium atoms are bombarded with particles such as free neutrons. When a neutron hits a nucleus, the nucleus splits into two smaller nuclei, releasing a lot of energy. In the reaction, called the chain reaction, some of the neutrons in the uranium nucleus fly away and hit other nuclei. These collisions, in turn, cause the other nuclei to split, releasing more energy and more neutrons. The process can continue explosively, as in an atomic bomb. In nuclear reactors, nuclear fission must be controlled. Typically, metal rods are inserted to trap certain neutrons and slow down the reaction. In fact, there are very few examples of purely mechanical systems. A pendulum does not swing forever. After a while, the swings become smaller and eventually stop. This happens because the mechanical energy of the pendulum is converted into thermal energy by a force called friction.
Friction is a force that resists the slippage or roll of one object on another. This force converts mechanical energy into thermal energy when two pieces of matter move against each other – for example, when a person rubs their hands to warm them. Chemical energy can be thought of as a form of microscopic (“stored”) potential energy. Chemical energy is stored in the bonds of chemical compounds and can be released during a chemical reaction when the compounds are modified. Radiant energy sources include the entire spectrum of electromagnetic radiation, 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. Radiant energy, for example, is not the photon itself, but you can see the energy as light and feel it as heat when the photons it is connected to arrive on the skin. Radiant energy is the physical energy that results from electromagnetic radiation and is usually observed when it radiates into the environment from a source.
Electromagnetic radiation is made up of tiny particles called photons – think of them as small packets of energy. Yes, the sun produces a lot of radiant energy, which is transmitted to the earth in the form of light. The use of electrical energy is of great importance in the modern industrial world. Electric currents turn the motors and drive the machines. Electric currents provide energy for labor-efficient appliances such as power tools, vacuum cleaners, and dishwashers. Obviously, currents can work and therefore have energy. Light energy is also very fast – in fact, nothing travels faster! Since the charges that cause energy move, electrical energy is a form of kinetic energy. To understand chemical energy, it is necessary to study what happens during a chemical reaction. All matter is made up of tiny units called atoms. An atom can bind to other atoms to form a group called a molecule. Atoms and molecules are the basic building blocks of matter – like stones, wood, air, soil, water and living things. Chemical energy is what holds atoms together in a molecule.
The second type of nuclear reaction is more difficult to create and control. It takes advantage of the fact that very small nuclei, such as hydrogen and its isotopes, require slightly more energy per proton and neutron than slightly heavier nuclei. (The situation is exactly the opposite of the uranium nucleus, where lighter nuclei require less energy.) When two hydrogen nuclei can be combined to form a heavier nucleus, a large amount of energy is released. This type of reaction occurs in the sun. Through a series of somewhat complicated reactions, four hydrogen nuclei combine to form a new helium nucleus, which releases a lot of energy. This compound of nuclei is the source of all the energy emitted by the sun. “Radiant energy.” Merriam-Webster.com Dictionary, Merriam-Webster, www.merriam-webster.com/dictionary/radiant%20energy. Retrieved 12 October 2022. Radiant energy is the energy transmitted by electromagnetic radiation. Light is a type of electromagnetic radiation. Some other types of electromagnetic radiation include X-rays, radio waves, and microwaves.
Radiant energy moves in waves. It can move in an empty space, air or even solid substances. Radiant energy is caused by accelerated electric charges or by electric or magnetic fields that increase or decrease over time.

Short electromagnetic waves contain more energy than long waves. The Sun is the closest star to planet Earth and emits light energy. For centuries, scientists have thought that matter and energy are completely different.
But at the beginning of the 20th century, Albert Einstein came to the conclusion that matter and energy are closely linked. He realized that matter (as mass) could turn into energy and energy into mass. Einstein quantitatively described the relationship between mass and energy in the famous equation E = mc2. In this equation, E represents energy, m is mass, and c is the speed of light (which is a constant). The change in mass given by this equation is m = E/c2. Since c2 is a very large quantity, E must actually be very large for m to be observable. This relationship has been confirmed experimentally. (See also Einstein, Albert; Theory of relativity.) The most frequently cited example of radiant energy is light. This is partly because light is a visible energy. We can see or feel energy.
In many cases, we do not see or feel energy, but we can only measure it with special instruments. Light is also the most widespread radiant energy because it is not just light, but a sum of many forms of energy. Although electromagnetic radiation can be described as movement in continuous waves, it can also be described as consisting of separate particles. These particles are tiny packets of energy called photons. Light and other forms of electromagnetic radiation actually have certain wave properties and particle properties. (See also Physics, “The Problem of Explaining Light”; Quantum mechanics.) What can generate radiant energies? Anything that has a temperature can produce radiant energies, provided that its temperature is different from absolute zero. Radiation is energy that moves from one place to another. Light, sound, heat and X-rays are examples of radiation. The different types of radiation fall into a few general categories: electromagnetic radiation, mechanical radiation, nuclear radiation and cosmic rays.
