The wavelength is defined as the distance between two successive points in the same phase of a wave motion, for example, the distance between two crests or between two successive wave breasts, and electromagnetic radiation.

The wavelength is inversely proportional to the frequency, ie the number of repetitions per unit time, usually seconds.

Longitud Cuando an airline pilot or captain of a cruise want to communicate via radio its position on the planet, it have two numerical values, which form a coordinate, called latitude and longitude. These are angles, measured in degrees, minutes and seconds of arc. Such classifications, however, can be shortened depending on the context, omitting "arc", provided it is understood that we are not talking time.

The latitude lines intersect the earth from side to side, and measure the angle formed between any part of the planet and its center. Thus, the globe has a series of rings that surround it, where passing through Ecuador has the largest diameter and located at the poles are just points.

Furthermore, a number of lines connecting the poles and having constant length; are called meridians. They cross the Ecuador, which is divided into 360 degrees; thus, to know the length of a given point, just know what latitude angle in question falls meridian.
