With the underlying advantage being deployment for high-throughput scanning and spectral imaging over a conveyor processing line, hyperspectral sensors introduce new inspection techniques that ...

Studying the line spectra produced by hot gases and absorbed by cooler gases allows us to identify the elements in stars. When a gas is very hot, it doesn’t emit all wavelengths of light.

1\). Line spectra are produced when electrons move from one energy level within an atom to another energy level. \(2\). The energy levels in the atom have definite values. \(3\). Line spectra are ...
