Answer:
The sound energy travels through the air into the microphone and makes the diaphragm inside vibrate. The sound energy in your voice makes the air vibrate. Vibrating air carries the sound energy into the phone. The diaphragm in the mouthpiece microphone converts sound energy into electrical energy.
Explanation: Hope this helps! :)
1) use energy from food
2) get rid of wastes
3) maintain
Light travels in electromagnetic waves in the form of photons. What do photons travel in? Can a frequency have weight? Carry weight? According to Einstien a photon with energy proportional to its frequency basically explains ultraviolet light(among other things), so does that mean light travels within a "larger" version of itself?
We know that light doesn't need a medium through which to travel because the speed of light is experimentally constant: independent of the movement of the source or detector or the direction in which it travels.
Light contrasts with sound, which travels through the air (or some other material medium). If you're stationary with respect to the air, then the speed of sound is the same in all directions. But if you're moving with respect to the air, the speed of sound will be the same in all directions relative to the air---which means that sound coming up in front of you will seem faster and sound catching up to you from behind will seem slower.
If light were a disturbance in a medium, it would exhibit the same behaviour. But light never does---its speed is the same under all circumstances. So it does you no good to postulate an aether. You can still do it, but it makes the theory more complicated than necessary. The only reason to postulate an aether is that you're uncomfortable with the idea of waves not needing a medium. But our modern understanding of quantum mechanics is that all kinds of particles have a wavelike nature, so, if you accept that matter can travel through empty space, you should have no problem accepting the same for light.
so it's true
