It is “organized” — each photon moves in step with the others. This means that all of the photons have wave fronts that launch in unison. The light is very directional. A laser light has a very tight beam and is very strong and concentrated. A flashlight, on the other hand, ...
One of the wave-like properties of light is frequency. The frequency is how fast a photon of light vibrates. The frequency determines the color; high frequency light is violet in color, whereas lower frequency light is red. Frequency is inversely proportionate to wavelength–the higher the freq...
The index of refraction is the difference between how fast light travels through a medium and how fast it travels through a vacuum. For example, the speed of a wave of light can change as it travels through air, water, glass, different gasses and different types of film. Sometimes, this ...
How fast are particles moving in the Large Hadron Collider? How Higgs bosons give mass? Is there an anti-Higgs boson? Why is the Higgs boson important? Why is the Higgs boson so important? What is a boson particle? How strong are the Large Hadron Collider magnets?
perceive light as moving away from them at more than 670 million mph. (That's because moving really, really fast is one of the only confirmed methods oftime travel— time actually slows down for those observers, who will age slower and perceive fewer moments than an observer moving slowly....
What is the speed of a photon? What is relativistic momentum? What particle travels faster than the speed of light? What is time dilation in special relativity? What is the speed of electromagnetic radiation in free space? Why can an object with a nonzero mass never travel as fast as the...
A natural source of ionizing radiation is radon, a radioactive material found underground. X-rays are a good example of man-made ionizing radiation. The three types of ionizing radiation we're going to discuss here are alpha particles, beta particles and rays. Particulate radiation involves fast...

When the fast-moving electrons collide with other electrons and ions, they release vast amounts of energy. This energy is what gives plasma its unique status and unbelievable cutting power. Commonplace Plasma Almost 99 percent of all matter in the universe is plasma. It's not common on Earth...
How Fast Is Quantum Entanglement? Scientists Clock the Speed of the Instantaneous Shattering the Limits of Classical Physics: Quantum Entanglement Measures Earth’s Rotation Like Never Before Challenging Traditional Theories – Physicists Develop New Method To Quantify Quantum Entanglement ...
