text: A plane wave seems to travel in a definite direction, and has constant value over any plane perpendicular to that direction.
text: Since the 19th century, oceanographers, meteorologists, engineers and ship designers have used a statistical model known as the Gaussian function (or Gaussian Sea or standard linear model) to predict wave height, on the assumption that wave heights in any given sea are tightly grouped around a central (the average of the largest third) value, known as the 'significant wave height'.
text: That is, its value is constant on a plane that is perpendicular to that direction.
text: In physics, a plane wave is a special case of wave or field: a physical quantity whose value, at any moment, is constant over any plane that is perpendicular to a fixed direction in space.
text: propagation n → {\displaystyle {\vec {n}}} with velocity c {\displaystyle c} ; and the value of the field is then the same, and constant in time, at every one of its points.
