Spectroscopy is a study that helps determine the properties of matter by measuring the light it absorbs and emits. This light energy is represented in the form of colors that cannot always be seen by the human eye, but they exist in the form of radiation. The strength of this radiation is measured by determining its wavelength. This, in short, is the basic explanation of what the term means.
In order to understand the concept of spectroscopy, it is necessary to understand some fundamentals that will lead to a complete picture of the study and how useful it is to humanity. This guide that we bring you here is for the beginner to understand the basics of the concept in order to get a clearer idea about it. Read this beginner’s guide to the basics of spectroscopy to understand the study in more detail and in greater depth.
What is light
In order to understand the broad concept, you must first recognize what light really is. Long ago, people thought that our eyes could see an image when the light is directed towards the eye and reflected on the object. It later turned out to be the opposite.
The light has to fall on an object in order for its image to be reflected by our sight. This sparked the interest of scientists in understanding what light really is. After many studies, scientists were able to discover this light is actually a type of electromagnetic radiation that our eyesight can perceive. They also realized that our eyesight can only see a range of wavelengths and that there is more radiation that we cannot see.
After discovering the concept of spectroscopy, scientists used a glass prism to measure the energy of light. Interestingly, the famous rock band Pink Floyd used this prism, which shows the visible colors in the spectrum. These visible colors are the seven colors of the rainbow. Unfortunately, the rainbow at the other end doesn’t have a pot of gold or a goblin sliding down on it. This is simply because the rainbow represents a specific area of ​​light energy emitted, absorbed, or reflected by an object. In summary, it can be said that this intangible, but extremely strong radiation determines what an object consists of.
The meaning of the invisible light
As already mentioned, there is only a limited range of wavelengths in which light and color are visible to us. The other invisible light colors are rather extremely powerful. These invisible radiations include x-rays, ultraviolet rays, gamma rays, and infrared light. Each of these invisible rays of light, after PASCO, has decisive advantages for mankind. For example, X-rays allow us to see the inner parts of our body, such as bones, and learn so much about their structure. Gamma rays, on the other hand, are the radiation used for MRI scans that help doctors determine brain activity in the area being examined. This means that while certain lights and their colors are invisible, they are no less useful than those we can see.
Areas of Science and Spectroscopy
The definition of the term shows that it is a branch of physics, but spectroscopy is in different branches of science. Astronomers use it to study fallen objects from space to learn more about their properties and their place of origin. You identify the fallen object by its composition, be it a meteor or a dead star or anything else.
For physicists, the study is the basis of several subject areas. A great example of this is how they realized that there is an electromagnetic field that has tremendous power. The other branches of physics based on understanding spectroscopy are electrodynamics and quantum mechanics.
The concept of spectroscopy, as physicists, biologists, chemists, and many other scientists around the world explained, is how the eye forms an image that led to the creation of the camera lens, which is basically a replica of the human eye.
The term spectroscopy is made up of two words. The first word is ghost, which originally means ghost. The spectrum is the energy of light that is in the form of radiation. Electromagnetic radiations are similar to ghosts in the sense that they are immaterial but still exist. The other word that makes up the concept is skopein, which means to observe. The combination of the words leads to the definition known today that, to put it simply, one observes what the energy of light and color says about a matter. The definition reveals so much of what we understand today, and there is likely a lot more to be discovered.
