The discussion centers around the interaction of laser light with materials, specifically focusing on whether iron can absorb heat from a blue laser light at 404nm compared to copper. Participants explore the implications of atomic structure and electron behavior in different states of matter.
Participants express differing views on the mechanisms of light absorption and the conditions under which iron absorbs laser light. No consensus is reached regarding the specific interactions of iron and copper with laser light.
There are unresolved assumptions regarding the states of matter and the specific conditions under which absorption occurs. The discussion highlights the complexity of interactions between light and materials without reaching definitive conclusions.
This discussion may be of interest to those exploring material science, laser applications, or the behavior of light in different states of matter.
An isolated atom will have a line structure but, in the close presence of other atoms, the Pauli Exclusion Principle tells us that no two atoms can have the same quantum numbers. The presence of the other atoms (sufficiently close) will spread the lines into bands.philip porhammer said:so, the valance electrons in a lattice of Iron would change the frequency or bandwidth of an absorption line?
