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 b...
Light waves come in a continuous variety of sizes, frequencies and energies, a continuum known as the electromagnetic spectrum. Once Maxwell introduced the concept of electromagnetic waves, everything clicked into place. Scientists now could develop a complete working model of light using terms and...
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 VISOR (Visual Instrument and Sensory Organ) worn by blind engineering officer Geordi La Forge in the "Star Trek: The Next Generation"TVshow and films, and they're both essentially the same technology. However, Naumann isn't able to "see" invisible portions of the electromagnetic spectrum....
The electromagnetic spectrum is comprised of visible and invisible light. Living in the world of appearance, virtually everything is perceived at the speed of light. But it is a representational reality. Beneath and beyond it all, is the Truth of Being, known directly. ...
Of course, further along the electromagnetic spectrum, security cameras and nanny cams can already track individuals with ease. “You’ve got to remember: the context you get out of the camera is just crazy,” says Taj Manku, CEO of the Wi-Fi sensing company Cognitive Systems. “You see ...
But it also reflects the fact that where we humans often struggle to remember names, faces, and even the day of the week, computer memories are the closest thing we have to memory perfection. How exactly do these "remarkable rememberers" actually work? Let's take a closer look!
Infrared light is in the invisible portion of the electromagnetic spectrum. An IR remote control (the transmitter) sends out pulses of infrared light that represent specific binary codes. These binary codes correspond to commands, such as Power On/Off and Volume Up. The IR receiver in the TV,...
Atoms are proved to be semi-classical electronic systems in the sense of closeness of their exact quantum electron energy spectrum with that calculated within semi-classical approximation. Introduced semi-classical model of atom represents the wave functions of bounded in atom electrons in form of hyd...
