asked in category: General Last Updated: 21st March, 2020# How do you find the speed of a deep water wave?

**Speed**(m/s) = ✤

**Speed**(m/s) = 3.1 * square root(depth in meters) ✤

**Waves**travel faster in deeper

**water**. results in

**waves**being more parallel to shore. A

**shallow water wave's speed**is dependent on

**ocean**depth. If part of a

**wave**is in shallower

**water**then it will travel slower.

Subsequently, one may also ask, what is the speed of a deep water wave?

Seismic sea **waves** have a period of about 20 minutes, and **speeds** of 760 km/h (470 mph). Wind **waves** (**deep**-**water waves**) have a period of about 20 seconds. The **speed** of all **ocean waves** is controlled by gravity, wavelength, and **water** depth.

Also, what determines the speed of deep water waves? The **speed of deep**-**water waves** depends on the wavelength of the **waves**. We say that **deep**-**water waves** show dispersion. A **wave** with a longer wavelength travels at higher **speed**. In contrast, shallow-**water waves** show no dispersion.

Similarly one may ask, how do you calculate the speed of a water wave?

**Wave speed** is the distance a **wave** travels in a given amount of time, such as the number of meters it travels per second. **Wave speed** is related to wavelength and **wave** frequency by the **equation**: **Speed** = Wavelength x Frequency. This **equation** can be used to **calculate wave speed** when wavelength and frequency are known.

Does the depth of water affect the speed of a wave?

The **depth of water affects the speed** of these **waves** directly without having anything to **do** with the density of the **water**. The deeper the **water**, the faster the **waves** travel, and so **waves** will refract (change direction) when they enter deeper or shallower **water** at an angle.
