Microscopic Scale

Definition

The microscopic scale refers to the level of observation and analysis that focuses on the smallest components of a system, such as individual atoms, molecules, and subatomic particles. This scale is crucial for understanding the fundamental processes and properties that govern the behavior of matter and energy at the most fundamental level.
