Low-energy photons (such as radio) behave like waves, while high-energy photons (such as X-rays) behave more like particles. 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...
Ionizing radiation comes in three flavors: alpha particles, beta particles and gamma rays.Alpha particlesare the least dangerous in terms of external exposure. Each particle contains a pair of neutrons and a pair of protons. They don't penetrate very deeply into the skin, if at all — in fa...
Originating from Earth’s core and atoms themselves, magnetism is the invisible force that shapes our everyday lives. Here’s how magnets actually work.
We know that atoms are made up of small particles like electrons, protons, and neutrons. Protons and neutrons are made up of smaller particles and it is called quarks.Answer and Explanation: It depends on the particle, Electron is an elementary particle unlike proton and neutron, its charge ...
This became the central element of quantum theory: a complex, mathematical explanation of the mysterious world of atoms and the particles lurking inside them. And it was for this work on photoelectricity that Einstein won the Nobel Prize in Physics 1921....
According to the American Cancer Society,“RF radiation doesn’t have enough energy to remove charged particles such as electrons (ionize), and so is called non-ionizing radiation. Non-ionizing radiation has enough energy to move atoms in a molecule around or cause them to vibrate, whic...
Explain how oxygen molecules, O2, and ozone molecules, O3, work together to protect us from high-energy ultraviolet radiation. What is the function of greenhouse gases and how do they work? How does carbon dioxide enter the blood and how is it transported?
FTIR Analysis measures the infrared region of the electromagnetic radiation spectrum, which has a longer wavelength and a lower frequency than visible light. This spectrum is measurable in a sample when submitted to infrared radiation (IR). The basic theory at work is that the bonds between ...
How do particle accelerators work? The basic particle accelerator is built through placing a particle source (called a proton) at opposing ends of an insulated, evacuated tube (keeping out obstructive air and dust). The polarity between these particles stimulates their movement, in the form of a...
Alpha particles, beta particles, neutrons, gamma rays and cosmic rays are all known as ionizing radiation, meaning that when these rays interact with an atom they can knock off an orbital electron. The loss of an electron can cause problems, including everything from cell death to genetic muta...
