7. describe how you can produce each type of spectra. a spectrum type emission how it is produced: b…

Brief Explanations:

An emission spectrum is produced when atoms or molecules transition from a higher - energy state to a lower - energy state and emit photons. An absorption spectrum is produced when photons are absorbed by atoms or molecules as they transition from a lower - energy state to a higher - energy state. A continuous spectrum is produced by a hot, dense object (like a black - body radiator) or by a hot, low - density gas in front of a cooler background.

Answer:

A. Emission spectrum: Produced by atoms/molecules transitioning from higher to lower energy states and emitting photons. B. Absorption spectrum: Produced when photons are absorbed by atoms/molecules during transition from lower to higher energy states. C. Continuous spectrum: Produced by hot, dense objects or hot, low - density gas in front of a cooler background.
