IPA: /rɪˈfrækʃən/
KK: /rɪˈfrækʃən/
The bending of light or sound waves when they pass from one material to another, causing a change in direction.
The refraction of light through a prism creates a rainbow effect.
Refraction → It is formed from "re-" (meaning again) and "frangere" (meaning to break). The word describes the phenomenon of light bending or breaking as it passes through different mediums.
Think of light 'breaking' ('frangere') 'again' ('re-') as it travels through different materials, which helps you remember that refraction is about the bending of light.
