Does sound energy need particles to travel through?
Yes they do need particles to travel through!
Does light need particles to move?
Light is the visible form of electromagnetic radiation. All the forms of electromagnetic radiation travel at the speed of light, when they are traveling through a vacuum. A vacuum is a space which contains no particles. The space between the sun and the earth is mostly empty space. When light makes contact with a particle, the light interacts with the atoms of the particle. In chemistry, we learn how electrons interact with light. Visible light is composed of many colors. Each color has a specific frequency. Energy = Plank's constant * frequency This means each color of light has a specific amount of energy. Before the electrons absorbed the energy, the electrons are in their "ground" state. This is their most stable state. When electrons absorb a specific amount of energy, we say that the electrons are in their "excited" state. This is an unstable state. To become stable energy is released, and we see a specific light of a specific color. When you see a blue shirt, you are seeing the result of electrons releasing a specific amount of electromagnetic energy, in the form of blue light. What happened to the other colors in the visible light? The atoms absorb the rest of the energy. This causes the atoms to vibrate at a higher frequency. Now the atoms have more kinetic energy. Temperature measures the average kinetic energy of the atoms. So the temperature of the shirt is increasing. When sun light shines on a blue shirt, the temperature of the shirt increases. You may be wondering what all this has to do with your question! The energy of electron is called orbital energy. The energy of the vibrating atom is called kinetic energy. The light's energy was converted into orbital energy and kinetic energy. During this time, the light does not exist. When the blue light is emitted from the atoms, light does exist. During this process, the form of a specific amount of the energy is changing from white light to orbital energy to blue light. The rest of the energy is in the form of vibrational kinetic energy of the atoms. This form of energy is actually what we call heat energy. Average velocity = distance ÷ time Since the light did not exist for a specific amount of time, but the clock kept on ticking, the average velocity of the light is less than the speed of light in a vacuum. Light does not need particles to travel. But the particles need the energy of the light to be seen by us and to experience some heat energy.
Is light a renewable resource of energy?
Light IS energy; it is not a SOURCE of energy. You can convert one form of energy into another, if you need to.
Does fire need energy?
No because it already is an energy.
Does sound transfer momentum?
Sound is the propagation of acoustic energy through a medium such as air or water. Although the energy propagates as waves, like light or other electromagnetic energy, acoustic energy is ''mechanical'' energy. Unlike light, where the waves can also be interpreted as particles, sound waves propagate through the oscillation of particles in a medium. The individual particles of air or water don't actually move very far, they just oscillate in place carrying the sound wave further to the next particles ahead. This is why sound doesn't propagate in a vaccuum but light does; sound requires a medium of particles to propagate the acoustic energy while light sort of propagates itself. Although the individual particles propagating the sound wave have mass and momentum while they're in motion, the wave itself has no momentum. So sound waves don't have a dual nature. However, you can transfer energy with sound--and do work--because the individual particles have energy and momentum as they oscillate. Air molecules inside your ear set into motion by the energy of an acoustic wave hit your eardrum and transfer their momentum to it which cause it to vibrate, which lets you hear the sound. Acoustic energy has even been used to levitate small objects against gravity--but you need a very loud sound to do that. You can find out more about this by searching the web for "acoustic levitation".

Yes they do need particles to travel through!
What is the minimum amount of energy that particles need to react when colliding is called the energy?
This energy is the activation energy.
Does photosynthesis need the suns heat energy or the suns light energy?
Light energy.
What a cell need to transport particles by active transport?
Energy
What does a cell need to transport particles by active transport?
Energy
Why do you need light in photosynthesis?
We need light in photosynthesis as Light provides the energy source. The process is based on light. The plants use light to convert energy. The same reason that we need air to breath.

Can a wind produce energy on its own?
Wind energy can provide all the energy that we need
Where does a firefly get the energy to light up?
Animals get all the energy they need from the food they eat.
Does fire need energy?
No because it already is an energy.
How fast does an object need to move to break the speed of sound?
Light travels at 186,000 miles per second, which means you have to travel faster than that to break the light barrier. This feat is technically "impossible", since the faster you move, the more mass you have and the more mass you have, the more energy is required to move you, and by the time you reach the speed of light, you will need to have infinite energy. This doesn't apply to light particles, since they have no mass.
