Is a spectrum of the electromagnetic radiation emitted by a substance
Is a spectrum obtained by transmitting electromagnetic radiation through a substance
Production conditions/ Energy consumption
Produced when excited atoms release energy and obtain a lower energy level
Produced when atoms absorb energy and obtain a higher energy level
Result
Shows different colored lines in the spectrum
Shows dark lines or gaps in the spectrum
Emission/Absorption of wavelengths
Account for wavelengths emitted by a substance
Account for wavelengths absorbed by a substance
Application
Is used to determine the composition of a certain substance as every element in the substance has a different emission level and radiates different amounts of energy
Is used to determine the number of substances in a sample and also to determine ability of a certain object to retain heat and its absorption level
