Photon Absorption
Quick fact
When a photon is absorbed by an atom, it causes the atom's electrons to move to higher energy levels, creating an 'excited' state that can lead to various physical or chemical changes.
Why this is interesting
Have you ever wondered how your skin tans when exposed to sunlight? The answer lies in a process called photon absorption, where light energy is captured by atoms and used for chemical reactions.

Understanding Photon Absorption
Imagine a tiny ball (an electron) sitting in a well-defined spot on a playground (an energy level). When a photon (a packet of light energy) hits the ball, it gives the ball enough energy to jump to a higher platform. This process is called photon absorption and is central to how matter interacts with light.
A deeper explanation
Photon absorption occurs when a photon's energy matches the difference between two energy levels in an atom or molecule. The absorbed energy allows electrons to move from a lower energy state (ground state) to a higher one (excited state). This process is essential for phenomena like photosynthesis, where plants use light energy to produce food, and it also plays a role in technologies such as solar panels and laser systems.
