Electromagnetic Radiation facts
While investigating facts about Electromagnetic Radiation From A Luminous Body and Electromagnetic Radiation Spectrum, I found out little known, but curios details like:
The S Pen in the Samsung Galaxy Note devices doesn't have its own battery. Instead, it makes use of electromagnetic fields radiating from the device itself to power itself via magnets and electromagnetic currents
how electromagnetic radiation is produced?
Tin foil hats really work to reduce the amount of radiofrequency electromagnetic radiation that gets in your noggin!
What electromagnetic radiation has the highest frequency?
In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what electromagnetic radiation has the shortest wavelength. Here are 13 of the best facts about Electromagnetic Radiation Definition and Electromagnetic Radiation Examples I managed to collect.
what electromagnetic radiation has the longest wavelength?
-
The observable universe is a spherical region of the Universe comprising all matter that can be observed from Earth at the present time, because electromagnetic radiation from these objects have had time to reach Earth since the Big Bang. Everywhere has its own observable universe
-
In 1888 Heinrich Heinz published his findings on electromagnetic radiation or radio waves and Professor Righi had done research on Hertz's work and shared some of his work with Marconi who continued to experiment with wireless telegraphy.
-
He proved Maxwell's theory that light and heat are electromagnetic radiations.
-
Of all the forms of radiation and light on the electromagnetic spectrum, humans can only visibly see a very small amount of light.
-
Light is also called electromagnetic radiation when speaking of light other than visible light.
-
The shape of the Hammerhead shark's head is used to detect electromagnetic radiation, such as the nerve impulses of a fish hiding in the sand, and acts as a sort of radar to help them scan wider areas of ocean in search of prey
-
In 1985 AT&T discovered that sharks would attack underwater fiber optic cables because they were attracted to the electromagnetic radiation they emitted.
-
The main reason eyes see in the "visible" spectrum" is because the earliest species to develop photosensitivity were aquatic, and only two specific wavelength ranges of electromagnetic radiation, blue and green visible light, can travel through water.
-
About Cherenkov Radiation, a phenomenon where electromagnetic radiation is emitted from an electron moving faster than the phase velocity of light (Kind of like a light sonic boom). This phenomenon causes water in underwater nuclear reactors to glow blue.
-
Gamma-Ray Bursts, the brightest electromagnetic events known to occur in the universe, if one were to occur in our galaxy and point directly to Earth it would deplete the ozone layer and radiation would destroy life on earth.
Why electromagnetic radiation is used?
You can easily fact check why electromagnetic radiation is used in satellite communication by examining the linked well-known sources.
A WHO Cellphone Radiation Cancer Risks Report says that "Radiofrequency electromagnetic fields are possibly carcinogenic to humans"
