Question

What is the means of Cross- Section?​

Answer 1

Answer:

In geometry, a cross section is the intersection of a figure in a 2-dimensional space with a line, or of a body in a 3-dimensional space with a plane, etc. When cutting an object into slices, one gets many parallel cross sections.

In physics, the cross section is a measure of probability that a specific process will take place in a collision of two particles. ... Cross section is typically denoted σ (sigma) and is expressed in terms of the transverse area that the incident particle must hit in order for the given process to occur.
