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.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
