Sound Travel from Water to Air - Visualizing the Possibilities

AI Thread Summary
Sound can indeed travel from water to air, and the reverse is also true. The speed of sound is significantly faster in water than in air, leading to notable reflections at the air-water interface. According to Snell's law, sound transitioning from water to air is refracted toward the surface normal, primarily directing sound upward. Visualizing sound is challenging since it is invisible, but understanding its behavior at the interface is crucial. This discussion highlights the acoustic properties and interactions of sound in different mediums.

can sound travel from a body of water to air?
if so, what might it look like?
 
Physics news on Phys.org
of course it does!
any data is greatly appreciated.
 
Yes, a sound can travel from water to air. Sound is invisible, so you could not see it.

The reverse is also true: sound can travel from air to water. And, you cannot see that, either.

Do you have a more specific question?

The speed of sound in water is considerably greater than in air. So you get a lot of reflection at the air-water surface. By Snell's law, sound going from water to air will be refracted toward the surface normal, so sound coming from the water into the air will be mostly directed upward, I think.
 
I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
