How do fast tsunamis travel in deep water?
Fast tsunamis travel in deep water because they have long wavelengths and low amplitudes, allowing them to move quickly with minimal energy loss. The speed of a tsunami is determined by the depth of the water it is traveling through, with deeper water supporting faster wave propagation. Tsunamis are not affected by surface friction in deep water, which also contributes to their fast travel speed.
How does wind speed affect tsunamis?
Wind speed itself does not directly affect tsunamis. Tsunamis are usually caused by underwater seismic activity, such as earthquakes or volcanic eruptions, which generate large waves that can travel across the ocean. However, strong winds can potentially impact the propagation of tsunamis by influencing wave height or speed in coastal areas.
Can a tsunami break the sound barrier?
The speed of the tsunami travelling trough the ocean is dependent on the ocean depth. The Mariana Trench is the deepest known part of the ocean with a depth of approx. 11000 meters. When a tsunami would travel over this trench it could theoretically reach a speed of approx. 330 m/s or 1180 km/h. To break the sound barrier at sea level, a speed of 1224 km/h needs to be reached. This means that there is no known earth condition where this phenomona could occur.
How do you calculate the speed of a tsunami?
Velocity = the square root of the quantity g times D. Where g is the acceleration due to gravity (9.8m/s squared) and D is the depth of the ocean water in meters. Extra help: 1 km = 1000m and 3600 seconds = 1 hour
Does sound velocity change based upon sound frequency?
No, sound velocity does not change based on sound frequency in a uniform medium. In a medium with a constant temperature and pressure, the speed of sound remains constant regardless of the frequency of the sound waves.
Does a tsunami go faster when the water is cold or warm?
There is no discernible difference in speed due to water temperature. The wave speed depends upon wavelength and the depth of the water for tsunamis at sea.

If you are changing the shutter speed why is the depth of field being affected?
Usually, one would change the aperture to compensate for the change in shutter speed in order to keep the level of exposure the same. Changing the aperture affects the depth of field.
Do tsunamis increase in speed over open oceans?
Yess
What term used to describe the rate of an objects movement?
Speed is the rate of movement in any direction based on change in position for a change in time. Velocity is a change in speed. It is also a change in direction while the speed does not have to change.
How fast are tsunamis in miles per hour?
Tsunamis can travel close to the speed of sound. The most recent one traveled at about 200 mph.
What is vertical speed?
Vertial Speed is final depth minus intitial depth divided by time
How do you calculate wave speed given the wavelength and the depth?
Wave speed = (wavelength) x (frequency) "Depth" (?) is not involved.

What happens to wave speed as the depth of the water increases?
As the depth of water increases, the wave speed tends to decrease. This is due to the decrease in wave amplitude as the wave energy is dispersed over a larger volume of water. The decrease in wave speed is also influenced by the change in water density and the effect of friction on the bottom of the water body.
How can we measure the depth of sea by using SONAR?
Simply by measuring the time it takes for the sonar 'ping' to return to the device that sent it. The speed of sound is constant - and dividing the time by the speed of sound gives the distance !
