You can read more about how photons work in How Florescent Lamps Work. EM radiation can travel through empty space. This differentiates it from other types of waves, such as sound, which need a medium to move through. All forms of EM radiation reside on the electromagneticspectrum, which ...
A series about radiation-immune teenagers rescuing the survivors of a post-meltdown Tokyo, this article argues that Coppelion presents three different strategies for addressing the subject of radiation that utilise either directly or indirectly characters’ emotions and their role within a science ...
When radiation of high enough energy strikes anatomin the human body, it can strip away an electron. The resulting positively charged atom is called anion, which explains why high energy radiation is called ionizing radiation. The release of the electron produces 33electron volts(eV) of energy, ...

How does electromagnetic radiation work? What distance does electromagnetic radiation travel in 0.42 ps? What does the energy of an electromagnetic wave depend on? What can detect electromagnetic radiations? Find the frequency of an electromagnetic wave with a wavelength of 2.9 \times 10^{-4} mete...
How Satellites Work "Man must rise above the Earth -- to the top of the atmosphere and beyond -- for only thus will he fully understand the world in which he lives." Socrates made this observation centuries before humans successfully placed an object in Earth's orbit. And yet the Greek ...
These are the values used by the U.S. government (NOAA) to convert radar site weather data into rain rates. One inch is 25 mm.Here's something to note. Any increase of 10 on a decibel scale, starting with dB, means the reflected radiation is TEN TIMES stronger. It doesn't mean ...
Let's take a look now at the ionization chamber. An ionization chamber is very simple. It consists of two plates with a voltage across them, along with a radioactive source of ionizing radiation, like this: The alpha particles generated by the americium have the following property: Theyionize...
