what factors determine the height length and period of a wave?
5700
List three factors that determine the height, length, and period of a wave. Waves are generated by winds blowing across the surface of the water. The main factors that determine wave characteristics are the wind speed, the length of time that the wind blows, and the expanse of water (fetch) affected.

Wavelength is the measure of the length of a complete wave cycle. The velocity of a wave is the distance travelled by a point on the wave. In general, for any wave the relation between Velocity and Wavelength is proportionate. It is expressed through the wave velocity formula.

The period of a wave is the time it takes to complete one cycle. The frequency is just the opposite; it's the number of wave cycles that are completed in one second. Amplitude and wavelength are both measures of distance. The amplitude measures the height of the crest of the wave from the midline.

['Crest = Highest point of the wave.', 'Trough = Lowest point of the wave.', 'Wavelength = Distance from one crest/trough to the next (m)', 'Wave Height = Height from trough to crest (m)', 'Wave steepness = ratio of wave height to wavelength.', 'Amplitude = distance from the centre of wave to the bottom of the trough (m)']

A wave has a wavelength λ, which is the distance between adjacent identical parts of the wave. The wave velocity and the wavelength are related to the wave's frequency and period by vw=λT or vw=fλ. The time for one complete wave cycle is the period T. The number of waves per unit time is the frequency ƒ.

The energy in a wave is determined by two variables. One is amplitude, which is the distance from the rest position of a wave to the top or bottom. Large amplitude waves contain more energy. The other is frequency, which is the number of waves that pass by each second.

Wave Anatomy Wave Height - The vertical distance between crest and trough. Wavelength - The horizontal distance between successive crests or troughs. ... Amplitude - One-half the wave height or the distance from either the crest or the trough to the still-water line.

Wavelength is also measured in metres ( ) - it is a length after all. The frequency ( ) of a wave is the number of waves passing a point in a certain time. We normally use a time of one second, so this gives frequency the unit hertz ( ), since one hertz is equal to one wave per second.

Several common wave characteristics include frequency, period, wavelength, and amplitude.

The basic properties (parts) of a wave include: frequency, amplitude, wavelength and speed.

They can be transverse or longitudinal. However, all waves have common properties—amplitude, wavelength, frequency, and speed. Amplitude describes how far the medium in a wave moves. Wavelength describes a wave's length, and frequency describes how often it occurs.

['Use a photometer to measure the energy of a wave.', 'Convert the energy into J s.', "Divide the energy by Planck's constant, 6.626 x 10-34, to get the frequency of the wave.", 'Divide the speed of light, ~300000000 m / s, by the frequency to get wavelength.']

AMPLITUDE AND WAVELENGTH The amplitude of a wave is the height of a wave as measured from the highest point on the wave (peak or crest) to the lowest point on the wave (trough). Wavelength refers to the length of a wave from one peak to the next.

The Wave Equation Multiplying the wave's frequency by its wavelength, which is its physical length, yields the velocity of the wave. The relationship can be expressed as velocity equals frequency times wavelength.

Three factors influence the formation of "wind waves": Windspeed; length of time the wind has blown over a given area; and distance of open water that the wind has blown over (called fetch).

The wave velocity and the wavelength are related to the wave's frequency and period by vw=λT or vw=fλ. The time for one complete wave cycle is the period T.

Wavelength is an important parameter of waves and is the distance between two like points on the wave. The wavelength is calculated from the wave speed and frequency by λ = wave speed/frequency, or λ = v / f.
