Wind wave may be written as: where C is speed (in meters per second), g is the acceleration due to gravity, and d is the depth of the water (in meters). The period of a wave remains unchanged regardless of the depth of water through which it is moving. As deep-water waves enter the shallows and feel the bottom, however, their speed is reduced and their crests "bunch up," so their wavelength shortens. As waves travel from deep to shallow water, their shape alters (wave height increases, speed decreases, and length decreases as wave orbits become asymmetrical). This process is called shoaling.
Distance between two straight lines equations of two non-vertical parallel lines the distance between the two lines is the distance between the two intersection points of these lines with the perpendicular line This distance can be found by first solving the linear systems and to get the coordinates of the intersection points. The solutions to the linear systems are the points and The distance between the points is which reduces to When the lines are given by the distance between them can be expressed as Distance between two straight lines The distance between two straight lines in the plane is the minimum distance between any
