A ghost is called a ghost: the appearance, in the world of the living, of the image of someone who is dead.
The first thing we are going to do is know the etymological origin of the term spectrum before entering fully into its definition. In this case, we can state that it is a word that derives from Latin, specifically from “spectrum”, which means “image” and that it is the result of the sum of two clearly delimited lexical components:
-The verb “specere”, which can be translated as “look” or “observe”.
-The instrumental suffix “-trum”.
Specter as ghost
The term spectrum has several meanings. The first meaning mentioned by the dictionary of the Royal Spanish Academy ( RAE ) refers to a ghost .
A specter, in this sense, is the appearance of the image of a deceased person in the world of the living . It is a kind of materialization of your soul or spirit.

When you leave that place, you will begin to constantly see the specter of a woman full of blood who was murdered some time ago.
In physics, the mode of distribution of the intensity of radiation according to a magnitude is called a spectrum.
Spectrum concept in physics
In the field of physics , the way in which the intensity of radiation is distributed according to a certain magnitude, such as energy or wavelength, is called a spectrum. The graphic representation of said distribution is also called a spectrum.
The visible spectrum , in this framework, is the portion of electromagnetic radiation that the human eye can perceive. This fragment of radiation is one that has between 400 and 700 nanometers in wavelength. In a similar sense, the audible spectrum is made up of the auditory frequencies that the human ear can register.
The light spectrum , for its part, is the result of the decomposition of white light as it passes through a refracting body. The spectrum generated by the dispersion of sunlight is known precisely as the solar spectrum .
The notion in medicine
For medicine , meanwhile, the spectrum is the group of microbe species against which an antibiotic is active in a therapeutic sense.
In the same way, we cannot ignore the existence of what is known as autism spectrum disorders .
