Any material that has a temperature above absolute zero gives off some radiant energy. It does not need a medium, such as air or metal, to take place. Radiant heat transfer is very important in the power industry because it is one of the most important ways to transfer thermal energy.
The quantity of radiant energy may be calculated by integrating radiant flux for time. The term “ radiant energy” is most commonly used in radiometry, solar energy, heating, and lighting. In physics, radiant energy is the energy of electromagnetic and gravitational radiation.
At its core, the Sun fuses 620 million metric tons of hydrogen each second.
The places where the most radiation is found are desert in nature and far from people, so this energy cannot be used for agricultural or industrial development.The Sun generates its energy by nuclear fusion of hydrogen nuclei into helium. You need a strong economic investment and not all consumers are financially prepared for this expense. When it becomes the type of energy chosen by the population, it needs large tracts of land, which makes it difficult to choose. The level of radiation that this type of energy fluctuates from one area to another and from one station to another. As technology advances day by day, the cost of radiant energy is reduced considerably, thus helping to maintain a proper economy.Īmong its main disadvantages, we can mention the following:. The solar radiation or capture systems it uses are easy to maintain, a circumstance that makes the choice easier. It is an energy use system considered ideal for all areas where the power line cannot reach or its transfer is very expensive and difficult. It is considered an inexhaustible source of energy because it is a type of energy that has no end. It is a type of non-polluting energy and perhaps one of its main advantages and characteristics. Advantages of radiant energyĪmong the main advantages of radiant energy that we can mention, we have: Radiant energy has the ability to move in a vacuum without occupying any kind of material, which is characteristic of electromagnetic waves. Radiant energy transmission units are photons that behave similarly to particles. Intensity is related to the number of photons that remain on a surface, while color is linked to the frequency and wavelength of the incident light. It is also obtained by means of solar electromagnetic pulses. It is a type of energy that can be obtained without the need for support material. Radiant energy is generated or obtained from electromagnetic waves, such as visible light, radio waves, and lightning. It can also be obtained from gamma rays and X-rays. It can also be obtained from radio waves, ultraviolet rays, and infrared radiation that corresponds to the thermal energy released by the bodies. Radiant energy can be acquired from different types of natural sources, among which we can mention the sun and the stars. They are all undulatory movements consisting of electric and magnetic fields. Since energy can be transformed into another type of energy, there are different forms of radiant energy related to nature. The best-known types of radiant energy are ultraviolet rays or X-rays. 
It is a type of energy that can be absorbed.It can be transmitted because you can travel through it.It is a type of reflected energy because it cannot penetrate matter, but rather jump.It forms a large number of waves of different lengths and frequencies.It is always on the move and travels at a speed of 300 thousand kilometers per second in space.It is a particle that is present in electromagnetic waves, gamma rays, ultraviolet rays (UV), infrared rays (IR), radio waves, visible light (electromagnetic spectrum), even in light and heat from the sun.It produces an interaction with matter to transfer a fixed amount of energy.It is transmitted by means of elementary particles known as photons.The main characteristics of radiant energy are as follows:
