Why do water surfaces have persistent "average wavelength" patches?
Have you ever stood above a river or lake and noticed that the surface has visible "patches"? It looks like the surface has different average wavelengths in some areas, leading to the light ...

Converting starting wave to known max wave height
in our university project, we are developing a tsunami simulation using the Shallow Water Equations. For our project, we have decided to allow users to enter an epicentre and the magnitude of an ...

Formation of wave ripple fields (in sand)
I've read a few articles about wave ripple fields:
https://www.coastalwiki.org/wiki/Wave_ripple_formation
https://en.wikipedia.org/wiki/Wave-formed_ripple
and a few others.
However, those two ...

Is the strongest acoustic signal always the closest?
I have a single beam echosounder that I use to measure the distance to an object underwater. It emits an acoustic pulse and listens to the reflections. Using the time of flight and the strongest ...

Is it possible to make large waves from perfectly timed single drops of water?
Assume I have a hemispherical container of water and an eyedropper. Is it possible to add water to the container one drop at a time, such that each drop continues to add kinetic energy to the water?

Are wind waves in a body of water different to disturbance waves?
This is something I have been wondering about since I have been thinking about tsunami. If you blow air across water it forms waves, if you throw a stone into water it also forms waves.
What I am ...

Can someone explain why waves shoal?
So, I was talking about Tsunamis with friends and as I started looking into it, I learned about the phenomena of shoaling. As water begins moving from deep areas into shallow areas, the waves increase ...

Why is it harder to hear someone underwater than on air?
Because water is denser than air, sound waves travel faster and with more energy in water than air. However, we are worse at hearing in water than in air. Why is this?
To clarify, I was comparing ...

Does a thin sheet of water reflect sound just as well as a thick layer of it?
It is very difficult to hear underwater sounds from above the surface of a body of water. This is suggested to be due to the speed of sound being very different in air versus water, leading to most ...
