In the physics classroom, content based on superheroes can be used in support of learning materials on topics such as optics, advanced materials, kinematics, and the electromagnetic (EM) spectrum. Studies have highlighted several student preconceptions with regards to different radiation types. For ...
While the shortest and longest wavelengths of the visible light could be the most visible, the most energy efficient and aesthetically pleasing waves are the shortwave infrared (SWIR) and microwave frequencies.UVUltraviolet (UV) radiation is a part of electromagnetic spectrum. It can be used to ...
Parts of the electromagnetic spectrum invisible to human eyes reveal a vast amount of information about the universe, but it took a long time for astronomers to learn how to view it. For thousands of years, humans were looking up at the star-studded night sky using just their eyes sensitive...
This article will explain how a hologram, light and your brain work together make clear, 3-D images. All of a hologram's properties come directly from the process used to create it, so we'll start with an overview of what it takes to make one. Special Thanks Special thanks to ...
EM radiation can range from very low energy to very high energy, and we call this span the electromagnetic spectrum. Within the EM spectrum, there are two types of radiation -- ionizing and non-ionizing. Feeling a bit overwhelmed? Don't worry, we'll explain all this in detail on the ...
When you've done that, you fire an electron beam down through the specimen from a giant electron gun at the top. The gun uses electromagnetic coils and high voltages (typically from 50,000 to several million volts) to accelerate the electrons to very high speeds. Thanks to our old friend...
The quantum helped explain why such a body emits radiation mostly in the middle of the electromagnetic spectrum, rather that in the ultraviolet as predicted by classical theory. Planck's explanation posited that light consists of discrete packets of energy called quanta, or photons, and that the...
Explain the relationships between the energy, wavelength, and frequency of electromagnetic radiation (light) in regards to the electromagnetic spectrum. Where do the waves from the electromagnetic spectrum come from? What are the types of electromagnetic radiation? How were electromagnetic waves ...
If the coil is free to move, it will do so—either toward or away from the permanent magnet. In an electric motor, the coil is set up so it can spin around on the spot and turn a wheel; in loudspeakers and headphones, the coil is glued to a piece of paper, plastic, or fabric ...
