Ive read that waves of any sort do not transfer mass, but only transfer energy. My question is why do I then float towards shore when at a beach and in the water. :uhh:
I think hallsofivy told you why, its because the bouy is near shore. If you are in the deep ocean, the no mass will be moved, only force.pallidin said:Water waves are directional, and they propagate as a force-carrier.
Show me a single experiment(minus wind) where a free-floating bouy does not also propagate, though slowly, with the direction of the wave.
Any takers?

The powder stays put in the same spot as the rippler creates constant parallel waves. Aftera few minutes small currents get created and the powder begins to move, but the waves themselves do not move the powder.
I'd like to show this, but our school has not got the approriate type of camera to record it. The demonstration is easily reproduceable though; pepper will make a suitable dust. put water in a baking sheet and create waves with a ruler. Be careful not to remove the ruler completely out of the water and don't move the ruler back and forth, just up and down slightly.
When we say that waves do not transfer mass, we mean that as a wave travels through a medium, it does not cause the particles of the medium to move along with it. Instead, the particles merely vibrate in place, and the wave itself carries energy through the medium.
Waves transfer energy through the transfer of momentum. As the wave travels through the medium, it interacts with the particles in the medium, causing them to oscillate. This oscillation transfers energy from one particle to the next, creating a wave that propagates through the medium without actually moving the particles along with it.
Even though waves do not transfer mass, they can still exert a force on objects in their path. This is because the energy carried by the wave can be absorbed or reflected by the object, causing it to experience a force. For example, when a sound wave reaches our eardrums, it causes them to vibrate, which our brain interprets as sound.
No, the behavior of waves can vary depending on the type of wave. Mechanical waves, such as sound waves and water waves, do not transfer mass. However, electromagnetic waves, such as light and radio waves, do not require a medium to propagate and thus do not transfer energy or mass through a medium.
Although waves themselves do not transfer mass, they can still cause objects to move. This is because the energy carried by the wave can be converted into other forms of energy, such as kinetic energy. For example, when ocean waves crash onto the shore, they can cause objects on the beach to move due to their kinetic energy. However, the wave itself does not transfer mass to these objects.
