Atomic Spectra and Energy Levels in Electromagnetic Radiation

Electromagnetic Spectrum

Range of all types of electromagnetic radiation.

Frequency

Number of waves passing a point per second.

Wavelength

Distance between consecutive peaks of a wave.

Energy Levels

Fixed distances from nucleus where electrons reside.

Ground State

Lowest energy state of an atom's electrons.

Excited State

Higher energy level of electrons after energy absorption.

Line Spectra

Spectra produced by electron transitions between energy levels.

Absorption Spectra

Spectrum showing dark lines where frequencies are missing.

Emission Spectra

Spectrum showing bright lines at emitted frequencies.

Discrete Energy Levels

Fixed values of energy for electron states.

Atomic Absorption Spectrum

Spectrum resulting from absorbed frequencies in gases.

Atomic Emission Spectrum

Spectrum resulting from emitted frequencies from electrons.

Electron Transition

Movement of electrons between different energy levels.

Radiation Absorption

Process of electrons absorbing specific frequencies.

Radiation Emission

Process of electrons releasing energy as light.

Unique Spectra

Distinct patterns of absorption and emission for each element.

Dark Lines

Indicate missing frequencies in absorption spectra.

Bright Lines

Indicate emitted frequencies in emission spectra.

Energy Absorption

Electrons gain energy to move to higher levels.

Energy Release

Electrons lose energy when dropping to lower levels.

Electromagnetic Radiation

Energy waves traveling through space at light speed.

Frequency and Energy Relation

Higher frequency corresponds to higher energy.
