l has various meanings in the Scientific & Educational category. Discover the full forms, definitions, and usage contexts of l in Scientific & Educational.
An empirical measure of the quantity of light. It is based upon the spectral sensitivity of the photosensors in the human eye under high (daytime) light levels. Photometrically it is the luminous flux emitted with a solid angle (1 steradian) by a point source having a uniform luminous intensity of 1 candela. Standard unit of measure for light flux or light energy. Lamp light output is measured in Lumens. It measures the rtotal amount of visible light emitted from any light source. It is SI derived unit of luminous flux. symbol is im.
Scientific & EducationalThe liter is a unit of volume.1 liter = 1000 cubic centimeters. There are many symbols used to represent a liter: L, l, and a lowercase cursive l. The most common is the capital L.
Scientific & EducationalAny of about 200 varieties of club moss. The commonest is the staghorn moss Lycopodium clavatum from which a resinous, reticulate-shaped pollen is obtained. This is commercially available and is characterized by a relatively spherical, uniformly sized particle (surface average diameter 29 mm, typically with 80 wt% contained within 25-35 mm) suitable for calibration purposes. When tested by non-inductive sparks in various dust ignition energy apparatus under the auspices of ASTM, its minimum ignition energy has been found to be about 20 mJ. This is believed to correspond to, or exceed, the maximum effective energy of bulking brush discharges.
Scientific & EducationalRefers to an optically active substance that rotates the plane of plane polarized light counterclockwise.
