Light Waves Flashcards
angle of incidence
The angle between the incident ray and the normal line.
angle of reflection
The angle between the reflected ray and the normal line.
continuous (variable)
A variable that has values that can be any number.
converging
Bringing rays of light together.
convex
A lens that produces converging rays of light.
diffuse reflection
Reflection from a rough surface.
dispersion
The splitting up of a ray of light of mixed wavelengths by refraction into its components.
emit
To give out.
incident ray
The ray coming from a source of light.
inverted
upside down
luminous
Gives out light.
medium
The material that affects light or sound by slowing it down or transferring the wave.
opaque
Objects that absorb, scatter, or reflect light and do not allow any light to pass through.
refraction
The change in direction of a ray or wave as a result of its change in speed.
source
Things that emit (give out) light or sound.
