Is synchrotron light coherent? How is alpha radiation created? Explain how you can create neon. How does a synchrotron particle accelerator work? How was dark matter discovered? How do lenses refract light? How does an atom emit a photon?
What color light is transmitted through a piece of blue glass? How do semiconductor lasers work? How does proton emission work? How does an excimer laser work? How are reflection and refraction manifested in sound? How does an atom emit a photon?
Light is a form of energy that can be released by an atom. It's made up of many small particle-like packets that have energy and momentum but no mass. These particles, called photons, are the most basic units of light. Photons are released as a result of moving electrons. In an atom...
An atomic clock is a clock that uses the resonance frequencies of atoms as its resonator. Basically atoms can be seen to resonate or “vibrate” as they absorb or emit energy. The electrons in all elements exist at different energy levels (it can help to conceptualise an atom as a positive...
Dr. Clark says that fires travelling slower uphill are an exception to the rule, but it does happen. Winds can work against a fire that is trying to move up a slope. "It depends on which way the wind's blowing," he said. "For example, I have a case study in Australia where the...
How Can a Diode Produce Light? Light is a form of energy that can be released by an atom. It's made up of many small particle-like packets that have energy and momentum but no mass. These particles, called photons, are the most basic units of light. Photons are released as a result...
— Surprise gamma-ray discovery could shed light on cosmic mystery Here's the problem that makes real-world gamma rays so dangerous. The number of electrons in the outer shell of an atom determines how that element interacts with other elements. Changing these interactions can lead to ...
Light is a form of energy that can be released by an atom. It is made up of many small particle-like packets that have energy and momentum but no mass. These particles, called light photons, are the most basic units of light. (For more information, see How Light Works.) Atoms release...
Some types of holograms use lasers that produce different colors of light as well. Depending on the type of laser you're using, you may also need a shutter to control the exposure. Lenses: Holography is often referred to as "lensless photography," but holography does require lenses. However...
In 1957, Parker was working as an assistant professor at the University of Chicago when he realized the superheated corona ofthe sunshould, in theory, emit charged particles at high speed, according to theUniversity of Chicago. (This superheating is one of the most mysterious aspects of the su...
