How is a sound wave a compression wave?
As a sound wave travels it compresses the air particles around it together in order for it to travel because a wave cannot travel if the matter it uses isn't connected.
What happens to the particles in a longitudinal wave as the amplitude increases?
the speed at which the energy travels increases.
Sound need particles to move does this mean it can travel in a vacuum?
No, they cannot. Sound waves are compression waves (mechanical longitudinal waves). This means they travel through mediums with the particles of the medium vibrating in the same or opposite direction of the wave, as opposed to perpendicular. Therefore, a sound wave needs particles to vibrate/oscillate for it to travel. If there are no particles, it cannot travel. A vacuum is defined by the absence of matter, meaning there are no particles. Thus, sound cannot travel in a vacuum.
What wave causes particles in matter to move back and forth along the same direction in which the waves travel?
A Compressional wave.
What happens to a sound wave if there are no particles to vibrate?
the sound wave will not make it to the ear drums. you wont hear the sound.
What does light travel in?
The simplest answer is that light consists of particles with wave properties. Elementary particles also have wave properties. This is how light travels.
Does particles in the medium do not actually travel with the wave?
They don't. The energy of the wave is transmitted from one particle (or group of particles) to another. The energy of the wave moves along, the individual particles return to their resting position.
What is a primary wave or p-wave?
Cause rock particles to vibrate in same direction that waves travel
How is a sound wave a compression wave?
As a sound wave travels it compresses the air particles around it together in order for it to travel because a wave cannot travel if the matter it uses isn't connected.
How do rock particles move during the passage of a P wave through the wave?
back and forth parallel to the direction of wave travel
What happens to particles of medium as wave propagated?
The particles of the medium will gain some energy. The exact effect will depend on the nature of the wave as well as that of the medium.
What happens to the particles in a longitudinal wave as the amplitude increases?
the speed at which the energy travels increases.
What must sound wave travel on to reach your ears?
sound waves travel through the air particles
What happens to the motion of the particles in a water wave as depth increases?
The motion of the particles in a water wave decreases as depth increases because the energy from the wave at the surface losses it's power.
Sound need particles to move does this mean it can travel in a vacuum?
No, they cannot. Sound waves are compression waves (mechanical longitudinal waves). This means they travel through mediums with the particles of the medium vibrating in the same or opposite direction of the wave, as opposed to perpendicular. Therefore, a sound wave needs particles to vibrate/oscillate for it to travel. If there are no particles, it cannot travel. A vacuum is defined by the absence of matter, meaning there are no particles. Thus, sound cannot travel in a vacuum.
How do the particles of energy in a longitudinal wave move?
In a longitudinal wave, the particles do not move with the wave. The particle movement is parallel to the direction of the wave propagation. This means that the particles move left and right which in turn makes the other particles start to oscillate. This creates a wave. longitudinal pressure waves are also known as sound waves.
Can sound waves travel through steel?
Yes sound waves are made from vibrating atoms or particles and so any medium which contains particles can allow a sound wave to travel through it. The only thing a sound wave cannot travel through is a vacuum.
