The lenght of time a wave has traveled or in more intelligent words The Fetch of a wave is the distance over open water over which the wind has blown (further it has travelled, the larger the wave.)

The fetch of a wave is the distance over which the wind blows without obstruction, generating waves on the water surface. A longer fetch typically results in larger and more powerful waves due to more time for the wind to transfer energy to the water. Fetch plays a critical role in wave height and energy.

What is a fetch wave?

The Fetch of a wave is the distance over open water over which the wind has blown (further it has travelled, the larger the wave.)


What determines how strong an earthquake will be?

1. Wind strength and duration 2. Fetch of the wave


Is georgio armani gay?

Fetch, often called the fetch length, is a term for the length of water over which a given wind has blown. It is used in geography and meteorology and is usually associated with coastal erosion. It plays a large part in longshore drift as well. Fetch length along with the wind speed (or strength) determines the size of waves produced. The longer the fetch length and the faster the wind speed, the larger and stronger the wave will be. For example, the winds which travel from the East Coast of the United States and hit the west coast of Ireland would have an extremely large fetch and would produce very large waves if the wind speed was also high. The fetch length determines the power and energy of the wave. Additionally, if the winds are blowing in the same direction during the wave's lifetime, the wave will in turn be stronger. If a fetch is very large, then the wave will be very large and vice versa. The fetch is related to the orbit of the wave. The longer the wind drags along the sea the more energy the wave will have which will make the wave a destructive wave.


What 3 things determine the size of a wave?

The size of a wave is primarily determined by the speed and duration of the wind that generates it. Additionally, the fetch, which is the distance over water that the wind blows in a continuous direction, also influences wave size. The longer the fetch and stronger the wind, the larger the waves produced.


How does the fetch of a wave affect its erosional power?

The fetch of a wave refers to the distance over which wind can travel uninterrupted across the water surface before generating waves. Longer fetch results in larger and more powerful waves due to the increased amount of energy that can be transferred to the water. This enhanced wave energy leads to greater erosional power, as the waves can carry more sediment and exert a stronger force on the coastline.


What is factors can affect the height of a wind formed wave?

The height of a wind-formed wave can be affected by factors such as wind speed, duration, and fetch (distance over which the wind has blown). Stronger winds over longer distances (fetch) can create larger waves, while shorter fetch or shorter duration of wind may result in smaller waves. The interaction between wind and the ocean surface also plays a role in wave height.


What is the height of the wave known as?

The height of a wave is the vertical distance between the wave's crest and trough. It is typically measured in meters, from peak to trough. The height of a wave can vary depending on factors such as wind speed, duration, and fetch.


What three things affect the size or a wave?

The three main factors that affect the size of a wave are the speed and duration of the wind that creates the wave, the distance over which the wind blows (known as the fetch), and the depth of the water.


What is meant by the term fetch in terms of geography and weather?

In geography and weather, the term fetch refers to the uninterrupted distance across which wind can blow over open water, generating waves. The longer the fetch, the larger and more powerful the waves can become. Fetch plays a key role in determining wave size, direction, and energy.


What are three things that can affect the size of a wave?

Wind speed, wind duration, and the distance over which the wind blows (fetch) can all affect the size of a wave.


Which are the three factors affecting wave energy?

The three factors affecting wave energy are the speed of the wind, the duration of time the wind has been blowing (fetch), and the distance over which the wind has been blowing (fetch length). These factors collectively determine the energy transfer to the water surface, leading to the generation of waves.


What does not affect wave height in deep water?

Water depth does not affect wave height in deep water. In deep water, the wave height is determined by the wind speed, duration, and fetch (distance wind has traveled over water).
