Definition of wavelength

wavelengthnoun

bước sóng

/ˈweɪvleŋkθ//ˈweɪvleŋkθ/

The word "wavelength" originated in the study of light and other electromagnetic waves. It combines "wave" - a concept used to describe the periodic oscillation of a disturbance - with "length" - referring to the spatial distance between two successive crests or troughs of a wave. The concept was introduced in the 19th century as scientists began to understand the wave-like nature of light and its different colors as different wavelengths. The term "wavelength" then extended to other types of waves like sound and radio waves.
