Absorption edge is a term used in physics to describe the point at which a material begins to absorb electromagnetic radiation. This point is characterized by a sharp increase in the absorption of radiation, which is caused by the interaction between the radiation and the electrons in the material.
Definitions
The absorption edge is defined as the point at which the absorption of electromagnetic radiation by a material increases sharply. This point is determined by the energy of the radiation and the properties of the material.
Origin
The concept of absorption edge was first introduced in the early 20th century by physicists studying the interaction of X-rays with materials. They observed that the absorption of X-rays by a material increased sharply at a certain energy level, which they called the absorption edge.
Meaning in different dictionaries
The meaning of absorption edge is consistent across different dictionaries. It is defined as the point at which a material begins to absorb electromagnetic radiation.
Associations
The absorption edge is associated with the properties of the material being studied. Different materials have different absorption edges, which are determined by the energy levels of the electrons in the material.
