... Light is composed of oscillating electromagnetic waves. The change in the electric field as a function of time can be represented by a vector that oscillates in one direction. Unpolarized light: The direction of the electric field oscillation is random. Linearly polarized light: The electric field o ...

Time in physics
Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.
