Amplitude - Amplitude is a nonnegative scalar measure of a wave's magnitude of oscillation, that is, magnitude of the maximum disturbance in the medium during one wave cycle.

Sometimes this distance . Used . is called the "peak amplitude", distinguishing it from another concept of amplitude, used especially in electrical engineering: the root mean square (RMS) amplitude, defined as the square roo. Used . t of the temporal mean of the square of the vertical distance of this graph from the horizontal axis. The use of peak amplitude is unambiguous for symmetric, periodic waves, like a sine wave, a square wave, or...

Ellipsoidals

Ellipsoidals is the colloquial term for a stage lighting instrument called the ERS (Ellipsoidal Reflector Spotlight), Profile Spotlight or Profile Spot. Other colloquial terms for the same device are Shakespeare or Leko, which is actually a brand name. Ellipsoidals are so named based on the shape of the reflector that they possess. The ellipsoidal contours capture and focus light through a cylinder containing a lens train or lens. Ellipsoidals are of different types and come in various sizes and shapes, each having its own particular qualities. Possessing optics with similar characteristics to a typical 35 mm slide projector, they are designed for a large variety of uses in the entertainment sector. They are also the most used among all types of stage lighting devices. They are called Profile Spotlights because the beams can be customized to readily take the shape of the object’s profile. Ellipsoidals are primarily required for more intense, clearly-outlined lighting requirements that offer greater flexibility. Source Four is yet another brand name for this type of lighting instrument. Normally, an ellipsoidal lighting unit has: an adjustable lens tube enclosing the lens or lens train; an ellipsoidal reflector; one or two Plano-convex or PC lenses; a set of bracing elements for holding the gel frames; two pairs of shutters mounted on an internally-located focal point; a metal gobo slot. The lamps in ellipsoidals are mostly rear-loaded, and either axially- or radially-mounted, with the base oriented up or down. Using the light wrong side up will result to a shorter lifespan.
