In physics, intensity is the power transferred per unit area, where the area is an imagined surface that is perpendicular to the direction of propagation of the energy. In the SI system, it has units watts per square metre (W/m 2).
The Ancient Greeks spoke Ancient Greek with three different major dialects: Aeolic, Doric and Ionic. They were the first Europeans to both read and write with an alphabet. This alphabet eventually led to the development of all modern European languages.
Greeks have always had their own language which was Greek. Greek is one of the world's oldest recorded living languages. The history of the Greek Language begins around the laâ¦te 3rd millennium BC. In the classical period, about 500 BC, there were three versions of the Greek language.
