wave theory
A theory that light behaves as a wave.
electromagnetic wave
A transverse wave composed of an oscillating electrical field and a magnetic field that oscillates perpendicular to the electrical field.
Quantum-mechanical theory of light
Current theory of light that it is composed of little packets of waves. Thus light is also thought of as a particle (photon).
visible spectrum
The light which we see with our eyes.
electromagnetic spectrum
Represents all wavelengths of light in creation.
The Law of Reflection
The angle of reflection equals the angle of incidence.
converging lens
A lens which makes all horizontal light rays converge to a single point.
diverging lens
A lens which bends light rays outwards, causing them to diverge away from one another.
additive primary color
The three basic colors (red, green, and blue) can be added together in different proportions to produce virtually any color.
subtractive primary colors
The colors cyan, magenta and yellow are colors that mix so as not to absorb all wavelengths of light.
