refraction

bending of light

diffraction

slight bending, spreading

absorption

absorbed by the atoms

straight line

as particles light travels in a

incident ray

hits a surface

reflected ray

the one that bounces off

regular reflection

smooth

specular reflection is known as

regular

irregular reflection

rough

diffuse reflection is known as

irregular reflection

concave

particle

portion of matter, smallest building blocks

Wave

disturbance that travels through time, energy transport phenomenon

constructive

crest meet, not aligned

destructive

waves cancel eo, aligned

theory of light as particle

newton

light as awave is said by

christian huygens

double slit theory is by

thomas young

said that light is wave and partivle

louis de broglie

wave interference

when 2 waves meet

red

refracts least

red

longest wavelength

red

lowest energy

violet

violet

highest frequency

violet

refracts most

scattering of light

light rays get deviated and strikes into obstacles

tyndall effect

colloidal particles

rayleigh scattering

scattering in atmosphere

scattered most:

short wavelengths

mie scattering

(particles)same or larger as wave of light

blackbody radiation

absorb all radiation

when temperature decreased

wavelength increases

better get ready when

your mistakes come back

stellar scintillation

twinkling of star

haloes

rings and arcs

sundogs

rainbow colored, part of halo

supernumerary bows

bows inside a rsinbow

mirage

repeated refraction of light

the refractive index of glass is 1.5 if the speed of light in a vacuum is 3.0x10^8 m/s find the speed of light in a medium

2x10^8 m/s

light travels in a medium at 2.5 x 10 ^ 8 m/s. the absolute refractive index is 1.2. what is the speed of light in a vacuum?

3x10^8 m/s

0.63

the speed of light in an unknown medium is 4.76x10^8 m/s. calculate the refractive index if c= 3.0 x 10 ^8 m/s

32 degrees

calculate the angle of reefraction in an air-water medium if the angle of incidence is 45 degrees. air =1 water = 1.33
