refraction Definition
- 1the bending of a wave, such as a light or sound wave, when it passes from one medium to another of different density
- 2the change in direction of a ray of light, sound, heat, or other energy as it passes through one medium into another of different density
Using refraction: Examples
Take a moment to familiarize yourself with how "refraction" can be used in various situations through the following examples!
Example
The refraction of light causes the pencil in the glass of water to appear bent.
Example
The refraction of sound waves can cause echoes and distortions.
Example
The refraction of seismic waves can help scientists understand the structure of the Earth's interior.
refraction Synonyms and Antonyms
Synonyms for refraction
- bending
- diffraction
- displacement
- deflection
Phrases with refraction
the angle between the refracted ray and the normal to the surface at the point of refraction
Example
The angle of refraction is always less than the angle of incidence.
a measure of how much a ray of light bends when it passes through a particular material
Example
Diamond has a high index of refraction, which makes it sparkle brightly.
the complete reflection of a ray of light within a medium such as water or glass, when the angle of incidence is greater than the critical angle
Example
Total internal reflection is what makes optical fibers work.
Origins of refraction
from Latin 'refractus', meaning 'broken up'
Summary: refraction in Brief
Refraction [rɪˈfrækʃən] refers to the bending of waves, such as light or sound, as they pass from one medium to another of different density. This phenomenon causes objects to appear distorted or displaced, as in the case of a pencil in a glass of water. Refraction is measured by the angle of refraction and the index of refraction, and can result in total internal reflection. It is a fundamental concept in optics and wave physics.
