A polarizer or polariser is an optical filter that lets light of a specific polarization pass and blocks waves of other polarizations. It can convert a beam of light of undefined or mixed polarization into a beam of well-defined polarization, that is polarized light. The common types of polarizers are linear polarizers and circular polarizers.
Length is a measure of one dimension, whereas area is a measure of two dimensions (length squared) and volume is a measure of three dimensions (length cubed).In most systems of measurement, the unit of length is a base unit, from which other units are defined.ength is a measure of one dimension, whereas area is a measure of two dimensions (length squared) and volume is a measure of three dimensions (length cubed).
Length is a measurement of how long something is. Width is a measurement of how wide it is.      Width and length are the sizes of an object in 2 dimensions which are â¦ 90 degrees apart. found this useful. acre = 43,560 square feet so for example: 100 feet long by 435.6 feet wide would equal one acre Length x Width = Square Feet Square Feet / 43560 = acres 208.71ft by 20 â¦ 8.71ft is equal to one acre. + 106 others found this useful.
