|
|
|
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.
|
|

visible spectrum
|
The light which we see with our eyes.

converging lens
|
A lens which makes all horizontal light rays converge to a single point.
|
|
