Atomic Spectra? WHAT?

Anytime an electron in an atom is excited (doesn't matter how), it relaxes back down, and in the process, emits a photon to get rid of the excess energy. The energy of the photon is directly proportional to the energy difference between the levels th...

just for surveying engineers!!!?

there are no surveying engineers, either civil engineers or land surveyors are the titles they go by. Try searching for theodolite, fundamentals of land surveying, transit, photogrammetry.

what types of materials produce.....?

Emission spectra are produced by physical systems with discrete energy levels, such as gases with bound electrons: isolated atoms, or gases not completely stripped of their electrons. Continuous spectra are produced by physical systems with a continu...
