Linear polarization: the electric field of light is confined to a single plane along the direction of propagation (Figure 1). Circular polarization: the ...
Light is a form of energy and like all energies, it is produced from a source. In Physics, these are called light sources.
The Element Vision task light offers a generous foot-print of glare free illumination in a single light source - not commonly found in LED computer lamps.

Light is traveling from left to right when the applet first initializes. Unpolarized white light is represented on the left-hand side of the window before the first polarizer by a set three sine waves that are colored red, green, and blue. These light waves are rotating about the propagation axis to represent that the fact that white light is vibrating in all planes perpendicular to the direction of propagation. Use the slider on the left to rotate the first polarizer. As the polarizer rotates, it changes the angle of the plane of light passed by the polarizer. Try this first.

Polarized light refers to light that has been filtered to vibrate in a single plane. It is especially useful in metallography for revealing the grain ...
Explore how light is polarized in a single plane by a polarizer and how that plane-polarized light must be oriented at a specific angle to pass through a second polarizer. To get a better understanding of the configuration presented in this tutorial, use the mouse cursor to reposition the light waves and polarizers to suit your tastes. To do this, place the cursor anywhere in the applet window, hold down the left mouse button, and roll the mouse around the screen. The light waves will follow.
2008919 — A ghost light is a single bulb left burning whenever a theatre is dark. Some argue that its function is to chase away mischievous spirits.

Ultraviolet light (UV), or more correctly, ultraviolet radiation (UVR), contains wavelengths of light just beyond purple on the visible light spectrum.

Fibre Optic Tails or light strands are sensory essentials for providing visual stimulation and offer a tremendous proprioceptive, tactile, and visual experiences. The soft glow of the colours and Sparkle Light effect offer a soothing and calming environment to relax, engage or move within. All TFH light sources use LED lights for bright even light (and never a bulb blown out), switch compatible for alternative interaction.

Light that is parallel to the computer monitor screen surface is represented by a flat sine wave. Light that is perpendicular to the screen surface is represented by a solid straight line. Light at any other angle is represented by a sine wave of lesser amplitude than that which is parallel to the monitor. When the second polarizer is parallel to the first polarizer, all light passing through the first polarizer also passes through the second. As the second polarizer is rotated through a 90-degree angle, the intensity of light decreases until it is totally blocked when the two polarizers are positioned at right angles with respect to one another.
