What type of energy does a loudspeaker produce?
The energy is in the form of sound waves, which are moving air molecules, a form of kinetic energy.
Why can light waves travel through a vacuum but water waves cannot?
That is correct. Light is a moving electromagnetic wave, and the energy it contains is carried in the moving electric and moving magnetic components of the wave. Light can move through a vacuum, and it would rather go through that than air or anything else (which scatters the energy). Sound is mechanical energy, and the energy of the sound is transferred into the medium through which it is travelling. As the energy of sound is carried by the medium, the vacuum of space will not support a sound wave.
Is energy carried on mechanical and electromagnetic waves?
Mechanical waves: These are waves which require a medium to travel through, i.e. sound (requires air molecules in the air). This type of wave transmits energy through the air molecules, however the medium itself does not move, hence in mechanical waves ENERGY IS CARRIED. Electromagnetic waves: These are waves which propagate electric and magnetic fields at 90 degrees (perpendicular) to one another, for example radio waves and light rays. Hence these waves DO TRANSMIT/CARRY ENERGY, despite the paradox of them being massless (photons have no apparent weight)
Is the movement of air from a fan kinetic energy?
If the air is moving, then it has kinetic energy. If the fan is running, then the blade has kinetic energy. Maybe that's where the moving air got its kinetic energy from. If the dog is also walking through the room, then the dog has kinetic energy too, but he probably didn't get his kinetic energy from the fan or the air. On the other hand, a piece of tissue floating through the room could very well have gotten its kinetic energy from the fan, but that kinetic energy had to be carried from the fan to the tissue by the moving air.
What are waves that need a media?
Mechanical wavesMechanical waves need a medium to move through. An example is sound moving through the air. Sound is a compressional mechanical wave and the medium is the air. That's why there isn't any sound in space.
Is waves moving through the air after a crash example of sound energy?
Yes.
How does sound waves travel in air and transfer energy?
As longitudinal waves. It transfers energy through vibrations of air layes
What contains sound energy?
As you may know, the sound energy is basically a wave or many waves traveling through the air( or anything that is not a void ) and those waves carry energy not matter. the sound waves or sound energy is a part of kinetic energy because the energy is not waiting to be unleashed, in fact it's moving within the air or any other material
Where do waves transfer energy?
they transfer energy through sound water and air.
What type of energy does a loudspeaker produce?
The energy is in the form of sound waves, which are moving air molecules, a form of kinetic energy.
What process is energy transferred when sound waves travel through the air?
Mechanical energy
What do scientists call the energy of a sound wave?
Sound is a form of energy derived from moving objects. Vibrations in air made by moving objects create sound waves.
What kind of energy travels in vibtating waves through the air?
electric magnet
How do scientist classify waves based on what they move through?
Scientist classify waves by moving through a medium and/or empty space. For example, a wall, air, water, space.
How is sound refected from surfaces?
Sound is mechanical energy. The energy displayed by the source is transferred into the medium through which it travels. When the wave, that moving energy, comes into contact with a surface, some of the energy is transferred into the surface. But how much? The more solid and "less moving" the surface (seen on a tiny scale), the less the moving air waves, those compression and rarifaction waves, can transfer energy into the surface. And that's what it's all about. The "softer" the surface, the more those pressure waves in air can affect that surface and transfer their energy into it.
Why can light waves travel through a vacuum but water waves cannot?
That is correct. Light is a moving electromagnetic wave, and the energy it contains is carried in the moving electric and moving magnetic components of the wave. Light can move through a vacuum, and it would rather go through that than air or anything else (which scatters the energy). Sound is mechanical energy, and the energy of the sound is transferred into the medium through which it is travelling. As the energy of sound is carried by the medium, the vacuum of space will not support a sound wave.
What is the form of energy that travels as waves through the air and some solids and liquids?
sound
