What is the radiation spectrum called?
This range is known as the electromagnetic spectrum. The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.
What is a spectrum of radiation?
electromagnetic spectrum, the entire distribution of electromagnetic radiation according to frequency or wavelength. The electromagnetic spectrum comprises the span of all electromagnetic radiation and consists of many subranges, commonly referred to as portions, such as visible light or ultraviolet radiation.
What are the three spectrum of radiation?
The electromagnetic spectrum
What is the difference between spectrum and radiation?
Electromagnetic radiation comes in a range of energies, known as the electromagnetic spectrum. The spectrum consists of radiation such as gamma rays, x-rays, ultraviolet, visible, infrared and radio.
Why do the different parts of the spectrum have different effects?
Electromagnetic radiation interacts with matter in different ways in different parts of the spectrum. The types of interaction can range from electronic excitation to molecular vibration depending on the different types of radiation, such as ultraviolet, X-rays, microwaves, and infrared radiation.
What is different about the different parts of the electromagnetic spectrum?
The different types of radiation are defined by the the amount of energy found in the photons. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays.
What are some differences between the parts of the EM spectrum?
What is the difference in electromagnetic spectrum and electromagnetic waves?
Radio waves, television waves, and microwaves are all types of electromagnetic waves. They only differ from each other in wavelength. The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.
What are the effects of EM radiation on different matter?
The main effect radiation has on matter is its ability to ionize atoms to become ions, a phenomenon known as ionization, which is very similar to the photoelectric effect. Radioactive particles or electromagnetic waves with sufficient energy collide with electrons on the atom to knock electrons off the atom.
What is the difference between electromagnetic waves and electromagnetic spectrum?
What is the difference between light and radiation?
In fact visible ‘light’ is a form of radiation, which can be defined as an energy that travels in the form of electromagnetic waves. Radiation, electromagnetic waves and photons are simply ‘light’.
How does the EM spectrum work?
Electromagnetic energy travels in waves and spans a broad spectrum from very long radio waves to very short gamma rays. The human eye can only detect only a small portion of this spectrum called visible light. A radio detects a different portion of the spectrum, and an x-ray machine uses yet another portion.
