SILICAMONDAY82 THE ELECTROMAGNETIC SPECTRUM DESCRIBES THE RANGE OF ELECTROMAGNETIC WAVES RANGING FROM VISIBLE LIGHT TO GAMMA RAYS. THIS IS AN IMPORTANT ... JANUARY 10, 2023 LEARNING THE ELECTROMAGNETIC SPECTRUM The electromagnetic spectrum describes the range of electromagnetic waves ranging from visible light to gamma rays. This is an important aspect of science, and knowing this area of the universe is crucial. In this article , I will discuss a few of the key aspects of this spectrum and how they function. Infrared Infrared is the spectrum of electromagnetic energy that goes past the red part of the visible light spectrum. The infrared spectrum is used to determine the temperature properties in objects. It is also utilized for night-vision equipment. Generally, infrared is classified into near infrared and far infrared. Near infrared is the wavelength range that comprises the shortest frequencies. These wavelengths are within the range of one to five microns. There are also intermediate and long infrared bands. Each has their own distinct wavelengths. The most well-known application of infrared is in night vision goggles for soldiers. These goggles convert infrared into the visible wavelengths for night viewing. Infrared light, however, is also used for wireless and wired communication. There is no evidence of a link between infrared and skin cancer. However, it is known that the International Commission on Non-Ionizing Radiation Protection (ICNIRP) has issued guidance on the exposure limits to invisible visible and infrared radiation. Visible light Visible light is one of the components in the spectrum known as electromagnetic. The Sun is the main sources of light. Other sources of visible light are the moon and stars. It is important to know that we are unable to see ultraviolet or infrared wavelengths. However, we can detect the red and blue light. These colors are mixed in what we call white light. There are numerous other obscure components to electromagnetic spectrum like infrared and radio waves. Some of these have been used for television, radio and mobile communications. However, the most effective way to make use of them is to design the appropriate kind of filter. By doing so we can limit the harmful impacts of these elements on our body. Similarly, we can create an environment in which we can examine these elements, even without using our own eyes. Although the longest and shortest wavelengths of the visible light may be the most visible however, the most energy efficient and pleasing to the eye are the shortwave infrared (SWIR) as well as microwave frequency. UV Ultraviolet (UV) radiation is a part in the spectrum known as electromagnetic. It can be used to serve a variety of purposes. However, it could also be harmful. UVB and UVC radiations are harmful for eyesight and can cause skin disease. This kind of energy can be absorbed by molecules and initiate chemical reactions. The absorbing molecule can then release visible light and emit fluorescence. The spectrum of the ultraviolet is divided into three main categories, namely, the extreme, near, as well as the middle. The most common sources of ultraviolet are lasers, arc lamps and light-emitting diodes. While UV rays have wavelengths that are shorter, UV Rays are smaller that those from X-rays, they are more powerful. This is useful for breaking chemical bonds. The waves are often referred to by the name of nonionizing radiation. In biochemistry the ultraviolet spectrum is commonly used to determine the absorption of a specific substance. There are a variety of substances that have significant light absorption bands within the UV. Ultraviolet light forms a part of electromagnetic spectrum, which is produced from the sun. Its spectrum spans between 10 and 400 nanometers and the frequencies range from 800 THz to 30 PHz. However, most people cannot be able to see it. X-rays X-rays are electromagnetic radiation that has high energy. In contrast to gamma rays and UV light, Xrays have wavelengths shorter than visible light, and are able to penetrate thin objects. They are used in a variety of medical applications, such as imaging bones and tissues. There are several kinds of X-rays. Hard X-rays are produced by the collision of an electron with the atom. The result is a void within the electron shell of the atom. Another electron could fill the vacancy. Alternatively, the incoming electron could kick out an atom. In this case, some of the energy from this photon gets transferred over to the electron scattering. The X-ray spectrum is not to be confused with the X-band which is a low-energy part in the electromagnetic spectrum. Although the two bands overlap by a few hundred nanometers, they don't have the same characteristics. Because X-rays penetrate, they can be used in a myriad of ways. For example, X-rays are employed in security screening procedures to find cracks in luggage. In addition, they are used in radiotherapy for cancer patients. X-rays are also used to discover the structural components of various materials like cement. Gamma rays Gamma rays are the most high-energy forms of electromagnetic radiation. In actuality, all high-energy photons are gamma radiations. They are generated through nuclear decay as well as high-energy Physics experiments. They are among the most energetic photons that are found in the electromagnetic spectrum. Because of their intense energy, gamma rays can be capable of piercing far into the material. It is possible for a gamma beam to penetrate several inches into lead. Many high-energy physics experiments create gamma rays. For instance the particle beam from a relativist focused by a magnetic field of hypernovas can be observed at the distance of 10 , billion light years. Certain gamma rays are released by the nucleus of some radionuclides when they go through radioactive decay. Gamma rays include atomic transitions as well as annihilation and sub-atomic particle interactions. what is the electromagnetic specturm of gamma radiation in astronomy are derived from other mechanisms. Gamma rays from supernovae as well as nuclear fallout are two of the most energetic electromagnetic radiation forms. They are a fantastic source to explore the universe. Certain gamma rays can cause damage to cells within the body. However, gamma rays are not as ionizing as beta and alpha rays, so it is more unlikely that they cause cancer. Nevertheless, gamma rays can affect the structure of DNA and may cause burns. Even the smallest amount of gamma rays may cause Ionization within the body.
