What else can I help you with?
Do cell phones use transverse waves or Compressional waves?
They use micowaves, so they are transverse (def. oscillations are perpendicular to the direction of wave propagation).
What is the Motion that occurs when you use a telephone?
electro-magnetic wave
What is the use of antennas?
an antenna is used for transmitting and receiving signals with the use of electro magnetic waves. without the antenna there will not be any communication between one end and the other end. so, antennas play an important role using the EM waves. these em waves take energy from conducting electrons and transmits the information to the other end.
What basic system do all maglev trains use?
[Electro]magnetism and superconductivity.
What do you use magnetic for today?
well you use a magnet to lots of things... from handbags to compasses!!unistation 360 plz like
What magnet do you use to purify water?
electro magnet or a very high powered magnet i no this because i am doing a science projet on this
What types of waves do cell phones use?
electromagnetic radiation in the microwave range some times cell phones use 50% uses and 50%health prombles overtimes don t uses
How are em waves use to measure distances space?
Electro-magnetic waves travel at approx 300 000 km per second in free space, so we may determine the distance to an object (say a reflector on the moon), by measuring the time from when we sent the pulse, to the time when the pulse is returned. AND divide that by two, for the EM wave travelled the distance twice.
What waves do MRI's use?
MRI uses magnetic fields and radio waves to measures how much water is in different tissues of the body, maps the location of the water and then uses this information to generate a detailed image.
Do EMP grenades exist in real life?
No, however you can have a machine to emit an electro magnetic pulse, but you can't use that technology in a grenade sized device
What is the difference between zapping device and electro magnetic device?
a zapping device is like a taser it can send a electric impulse into something like a human or animal to stun it. a electro magnetic device is something police will use to see if you have any metal or weapons on you and they are also used at airports to see if you have any metal or weapons on you to.
Do bats use radar?
No. Bat's use ultrasound (witch is a pressure wave) rather then radio frequency (electro-magnetic waves) and therefore are more like Sonar then Radar
