What are the matter interactions?
Light–matter interactions are fundamentally quantum electrodynamical, and in many cases, are described as quantum transitions by electrons, accompanied by the emission, absorption or scattering of quanta of the electromagnetic field in vacuum (photons).
What are the interactions of matter and light?
Light interacts with matter in a number of ways, including absorption, reflection, refraction, emission, and scattering. In this course we will focus on two of these: absorption and emission.
What is an example of the interaction between matter and energy?
For example, if you add energy to an ice cube made of water, it becomes liquid water, and if you add even more energy, it becomes steam. The kind of matter is the same, and the amount of matter is the same as in the original cube, but there is more or less energy.
What is the interaction between matter and energy called?
Physics the science of Matter and Energy and their Interactions Physics is the science of matter and energy and their interactions and motion through space and time. The science of change, including physical laws, physical properties and phenomena.
What is the interaction of matter and radiation?
The main effect radiation has on matter is its ability to ionize atoms to become ions, a phenomenon known as ionization, which is very similar to the photoelectric effect. Radioactive particles or electromagnetic waves with sufficient energy collide with electrons on the atom to knock electrons off the atom.
