Photons are elementary particles that act as the fundamental carriers of light and all other forms of electromagnetic radiation. They are unique because they have no mass and always travel at the speed of light in a vacuum. Photons exhibit both wave-like and particle-like properties, a dual na...
In summary, photons are fundamental particles of light that travel at the speed of light and have no mass. They are produced by the movement of charged particles within atoms and play a crucial role in the electromagnetic spectrum. Photons can be detected using specialized equipment and have ...
Chapter 13 Notes : Photons and Atomic Spectra How are the e-m waves emitted by atoms related to energy levels of electrons ?Planck, MaxThis, JBohr, Niels
Even so, all the atoms of a unit cell do not occupy the entire volume of the unit cell itself, there is always some space (or rather voids) between the atoms (assumed to be spheres). This means that ...
On absorbing adequate amount of energy, flowing inert gas atoms make the appropriate gap inherently, on split, thus, switching photonic current to photons on increasing wavelength and visible light reveal in the prescribed range of wavelength as is the case in a neon lamp. In silicon solar ...
then quanta of gravity called gravitons must be exchanged between them. In the setup, a microdiamond with a mass of roughly 1*10-11grams, a width of 2*10-6meters, and a temperature less than 77 Kelvin has one of its central carbon atoms displaced and replaced with a nitrogen atom. Fi...
atoms of a specific element are all the same, down to the very last atom; atoms of different elements can be told apart by their atomic weights; atoms of elements unite to form chemical compounds; atoms can neither be created or destroyed in chemical reaction, only the grouping ever changes...
of an atom could make. When we expose a gas to photons of all wavelengths, each electron in the gas may absorb a photon with exactly the right energy to excite it into the next possible energy level. Hence, the photons of an emission spectrum represent a variety of possible energy levels...
If many atoms are cooled to a very low temperature confined in a small volume, they can become indistinguishable and behave like a single “super particle.” Physicists also call this a Bose-Einstein condensate or quantum gas. Photons condense based on a similar principle and can be cooled usi...
All the atoms are composed of the nucleus with protons and neutrons as part of the nucleus. The nucleus may sometime get unstable due to some reason and achieve stability after undergoing a radioactive decay. This decay is of three types, alpha decay beta decay and gamma decay. ...
