Summary – Radiation vs Electromagnetic RadiationĮlectromagnetic radiation is a type of radiation. The below infographic presents the differences between radiation and electromagnetic radiation in tabular form for side-by-side comparison. The key difference between radiation and electromagnetic radiation is that radiation is energy that travels and spreads out as it goes, whereas electromagnetic radiation is a combination of waves of the electromagnetic field that can propagate through space and can carry electromagnetic radiant energy. The terms radiation and electromagnetic radiation are related to each other because electromagnetic radiation is a type of radiation. What is the Difference Between Radiation and Electromagnetic Radiation? Furthermore, the speed of electromagnetic radiation is the speed of light. This also determines how different wavelengths of the electromagnetic spectrum are produced. This depends on how this periodic change takes place and how the power is generated. These waves are generated due to periodic changes in the electric or magnetic field. Moreover, electromagnetic radiation contains electromagnetic waves that synchronize with oscillations of electric and magnetic fields. All these wave types tend to form a part of the electromagnetic spectrum. This includes radio waves, microwaves, infrared light, UV light, X-rays, and gamma rays. What is Electromagnetic Radiation?Įlectromagnetic radiation is a combination of waves of the electromagnetic field that tends to propagate through space and carry electromagnetic radiant energy. This type of radiation expands as it passes through space and also when the energy of this radiation is conserved, where the intensity of all types of radiation from a point source tends to follow an inverse-square law relative to the distance from its source. This leads to a system of measurements and physical units that are applicable to all types of radiation. The term radiation derives from the phenomenon of waves radiating from a source. Non-ionizing radiation, however, refers to any type of electromagnetic radiation that is not carrying enough energy per quantum for the ionization of atoms or molecules.įigure 01: Radiation Passing through Matter Generally, ionizing radiation carries more than 10 eV, which is enough to ionize atoms and molecules and break chemical bonds. This classification depends on the energy of radiated particles. ![]() Moreover, we can categorize radiation as either ionizing or non-ionizing radiation. There are different types of radiation, including electromagnetic radiation, particle radiation, acoustic radiation, and gravitational radiation. Radiation is the emission or transmission of energy in the form of waves or particles through space or material medium. Summary – Radiation vs Electromagnetic Radiation What is Radiation? Radiation vs Electromagnetic Radiation in Tabular Formĥ. Each of the style and weight combinations is called a face or typeface, and together they are, hopefully, a happy typeface family (rather than a disfunctional typeface family which will probably be more familiar to you).The key difference between radiation and electromagnetic radiation is that radiation is energy that travels and spreads out as it goes, whereas electromagnetic radiation is a combination of waves of the electromagnetic field that can propagate through space and can carry electromagnetic radiant energy. For example, Goudy Old Style has Roman (upright or normal), italic (slanted and cursive), bold and bold italic versions. Is a group of typefaces that were designed to be used together. Font and face still tend to be used interchangeably, although the term face is usually more correct.” Before scalable type, there was little distinction between the terms font, face, and family. ![]() Think of the font as a little piece of software that tells the computer and printer how to display and print the typeface.Īccording to Adobe’s type gloassary: “A font is one weight, width, and style of a So when you say “Arial” or “Goudy” you’re talking about a set of letters in a specific style.įont: is the digital file that contains/describes the typeface. The letters, numbers, and symbols that make up a design of type. Typeface: is the design of the alphabet-the shape of the letters that make up the typestyle. Confused by the terms? That’s probably because it’s confusing!īut here’s the simple way to think of it.
