What is the energy change takes place in microphone?
From sound to electrical and kinetic (vibrations)
Why the sound waves could not pass through vacuum?
Sound waves need to cause vibrations in a medium in order to travel. Vibrations cannot be created in a vacuum, as there is no matter present.
Why does sound travel slower through liquids?
It doesn't, sound travels slowest in air then faster in liquids then solids. Sound traveling through steel in many times faster then through air, for example. Sound travels through vibrations, and the vibrations pass through molecules until they reach your ear. If the molecules are far away it takes longer to pass the vibrations, but if they are closer together they will travel faster. Because the molecules are packed closer together in a liquid the sound travels faster through it, and even faster through solids.
Why do sounds travel quickly through solids and liquids but not gases?
because the particles are closer together so the vibrations are able to pass through them faster where as in gasses the particles are very spaced out so it takes longer to pass through the gas
Sound does not travel through a vacuum?
No. Sound is transmitted as vibrations, that pass from one group of atoms to the next, thus, it requires the presence of atoms that transport the sound wave.No. Sound is transmitted as vibrations, that pass from one group of atoms to the next, thus, it requires the presence of atoms that transport the sound wave.No. Sound is transmitted as vibrations, that pass from one group of atoms to the next, thus, it requires the presence of atoms that transport the sound wave.No. Sound is transmitted as vibrations, that pass from one group of atoms to the next, thus, it requires the presence of atoms that transport the sound wave.
When you speak what do the vibrations have to travel through to get to the microphone?
They travel through the air.
Do you need a microphone to talk to someone on the phone on gmail?
Yes, you will need a microphone to talk. It is the instrument through which your voice will pass. The microphone is an essential part of talking.

Why a throat microphone is best when it is very noisy?
Because it picks up vibrations directly from the person's voice-box - instead of receiving them through the air, where they mix with background sounds.
What Energy Transformations are in a Microphone?
Sound energy (vibrations in air pressure) are converted to electrical signals
What is the function of microphone?
A microphone converts the pressure waves caused by sound into vibrations within a coil which transforms the vibrations into electric signals. These electric signals can then be sent by wire or wireless to an amp or mixer of some sort for output to speakers or perhaps a recording device.
Can sound travel though soild?
Sound is vibrations, therefore sound can pass through most solids, liquids, and gases.
Why do sounds travel quickly through solids and liquids but not gases?
because the particles are closer together so the vibrations are able to pass through them faster where as in gasses the particles are very spaced out so it takes longer to pass through the gas
What mediums do sound move through?
Sound consists of a wave of vibrations of particles so it must have a material substance to pass through. So sound can pass through solids, liquids and gases but not through a vacuum. See http://www.school-for-champions.com/science/sound.htm
Why do electric guitars need pickups?
To amplify the vibrations of the strings, much like speaking into a microphone amplifies your voice.
