Absorpsie Quiz en Flashcards: Betekenis en Faktore

Study Notes

Definition and Explanation

Absorption is a process in which the energy of a photon is transferred to a molecule, atom, or ion.
It involves the transfer of energy from electromagnetic radiation to matter.

Types of Absorption

Atomic Absorption: occurs when the energy from electromagnetic radiation is absorbed by atoms, causing them to transition to a higher energy state.
Molecular Absorption: occurs when the energy from electromagnetic radiation is absorbed by molecules, causing them to vibrate or rotate more vigorously.
Ion Absorption: occurs when the energy from electromagnetic radiation is absorbed by ions, causing them to gain kinetic energy.

Factors Affecting Absorption

Concentration: increased concentration of the absorbing species increases absorption.
Path Length: increased path length of the radiation through the sample increases absorption.
Temperature: increased temperature can increase or decrease absorption depending on the system.
Pressure: increased pressure can increase or decrease absorption depending on the system.

Applications of Absorption

Spectroscopy: absorption is used to analyze the composition and properties of substances.
Dyes and Pigments: absorption is used to create colors and hues in materials.
Lasers: absorption is used to create population inversions and amplify light.
Climate Science: absorption of infrared radiation by greenhouse gases contributes to the greenhouse effect.
