As an ocean wave passes, the water moves up and down in a circular pattern and returns to its original position.
Light waves usually vibrate in all directions but what allows only light vibrating in a certain direction to pass through?
secondary waves or otherwise known as s-waves
How does the frequency of vibration of a small object floating in water compare with the number of waves passing it each second?
They are the same.
A cork floats on the water as a wave passes by What happens to the cork Will the cork's vibrational frequency be related to the water wave's frequency and if so how?
The cork will move up and down with the wave, since the wave is a transverse wave. I would think that the frequency should be the same as the wave.
Sound waves are waves of vibrations. When you speak, you vibrate a few air molecules, which vibrate and hit other air molecules, then more and more. when the molecules in your… ear vibrate, you hear sound. But really, you feel the vibrations. Then why do we say hear, instead of feel? Because we are already used to saying hear. you wouldn't come to your friend and say, "Speak louder! I can't feel you!"
How does the frequency of vibration of a small object floating in water compare to the number of waves passing it each second?
Is it true that loudness is determined by how often the particles in an object vibrate when a wave passes through an object?
No. Loudness is not determined by the wave's frequency, but by its amplitude. That's how much the particles of the object move (how large is the displacement).
Sound is energy of mechanical vibration transferred through a medium. Commonly the medium is air, but solids, liquids and gasses all transmit sound. Indeed, sound travels fa…ster through liquid and solids than through gas. Sound does not propagate through a vacuum.
No, they do vibrate to a degree as they are generally mounted to the engine and it vibrates but it should not vibrate due to its operation.
No, if the term "vibrating molecules" means vibrations within the individual molecules. It is not vibration of the individual molecules, but the "vibration" of regions of mole…cules that is the phenomena we call sound. Sound can travel in gas, liquid and solids, but this answer will address only sound in air since the other situations are similar. In air, vibrations of physical objects, like the human vocal cords or a drum, cause air next to the object to become compressed and rarefied as the object vibrates. When a region of air is compressed, it pushes outward and air movement occurs to nearby regions. When a region of air is rarefied, movement develops from the nearby regions towards the less dense regions. When an object vibrates, the compression and rarefaction process repeats with regularity and the regions of air movement develop regularity and those region propagate away from the vibration source. That propagation of compressed and rarefied regions of air is sound.
