Physics of light and human vision
Most relevant theories
Planck's quantum theory
Huygens wave theory
Newton's corpuscular theory
Maxwell's electromagnetic theory
Light is an electromagnetic wave
All the elements present in the environment reflect or absorb electromagnetic radiation
Visible spectrum 700nm-400nm
It's energy
It has a very short wavelength
V = 300,000 km/s (vacuum)
Speed decreases depending on the density of the medium
Goes in a rectilinear path
EMS / ELECTRO MAGNETIC spectrum
Human vision
Materials
Opaque
Do not allow light to pass through
Transparent
Allow the passage of light
Translucent
allow the passage of light partially
PHENOMENONS
REFLECTION
The change in direction experienced by a light beam after striking a surface
Snell's laws
1st law: the reflection is in the same plane
2nd law: the angles of the phenomenon are equal/constant
REFRACTION
The change in direction as it passes through a different density material
ABSORPTION
When a beam gradually decreases in intensity as it spreads through a
medium
The absorbed energy in the form of light is transformed into energy in the form of heat
INTERFERENCE
When two or more waves overlap each other
DIFFRACTION
The deviation of light that is caused in the profile of the objects that is found by spreading
POLARIZATION
The orientation of the oscillations of the light waves
COLOR
The chemical properties of the matter
The final chromatic sensation perceived by our brains
The properties of the light incident on the object
