Transcript of Absorption & emission spectrum starter
Absorption SpectrumPhoton is absorbed and excites electron to higher quantum energy state.
0 eV
-10 eV
hf
Ground state
ΔE
Absorption SpectrumAbsorption spectra always involve atoms going up in energy level.
0 eV
-10 eV
ionized
Emission SpectrumPhoton is emitted and electron drops to lower quantum energy state.
0 eV
-10 eV
hf
Excited state
DE
Emission SpectrumEmission spectra always involve electrons going down in energy level.
0 eV
-10 eV
ionized
Converting eV to Joules (J)
1 eV = 1.602 x 10-19J
