How to use refraction
Refraction is a technical term used primarily in physics, optics, and related scientific fields to describe the physical phenomenon of waves changing direction when entering a new medium. It is more precise and technical than the general synonym 'bending' and is the standard term in scientific and educational contexts when discussing how light behaves in water, glass, or the atmosphere.
Common phrases
- light refraction
- angle of refraction
- refractive index
- atmospheric refraction
- refraction of light
Synonyms
bending · deflection · deviation
Word family
refract (verb) · refractive (adjective) · refractometer (noun)
A common mistake
Learners sometimes confuse refraction with reflection (the bouncing back of light from a surface) or with diffraction (the spreading of waves around obstacles); refraction specifically refers to the bending of waves as they pass through materials with different optical densities.
