Southwest already serves more domestic passengers than any other airline, but near-international markets like Latin America and the Caribbean represent a big potential growth opportunity for the company. Southwest Airlines is breaking ground on a new international terminal in Houston.The Houston terminal is a big part of Southwest's international expansion plans. Houston is the fifth-largest U.S. metropolitan area, so it has plenty of local traffic, and it is well located to serve as a Latin American gateway.outhwest already serves more domestic passengers than any other airline, but near-international markets like Latin America and the Caribbean represent a big potential growth opportunity for the company.

The unit of measuring the brightness-or to use the precise scientific terminology, illuminance-in SI system of measurement is lux or lumen per square meter.Illuminance is measured in foot candles. One foot-candle is equal to 10.76 lux. Please note that lumen is the measure of total light emitted by a source of light.he total amount of visible light is measured in units of lumens. How bright it appears when it falls on a surface area is illuminance. When the same luminous flux falls over a larger area it will appear to be less bright. 1 lx = 1 lm/m^2 which in terms of the basic SI units is 1 cd*sr*m^-2.
different quantities, we will just use the word intensity to describe the relative brightness. of the light, although the term may not be strictly appropriate for your sensor. Regardless. of the way light is measured, the same relative changes with distance are observed, and. that is what you will study today. In this experiment you will measure light intensity at a. variety of distances from a small source of light, and see how the intensity varies with.
