can we hear the fm signal transmitted a year before today by tuning at same frequency??please clarify?

Question

the signals in general are a form of energy ..ie they can be transferred from one form to another but not desroyed nor created..so what happens to signals that are not recieved ???do they stay in air???or is there noise interfernce???Can we hear the song played at a particular station 5 days or say a year back by tuning it at same frequency today???if not why???

Answer 1

sad individual

(added)

to hear a signal produced 5 years ago, you'd need to be 5 light years away from the source

Answer 2

the electro-magnetic wave transmitted from an FM station is a travelling wave. you always hear it at a later time, depending on the distance travelled. If only a few miles then it is nearly instantaneous. If bounced off the moon, then several seconds. A reflector a half light-year distant could return the signal to Earth a year later. However the signal would become so weak due to dispersion, that no existing receiver would be sensitive enough to receive it.

Answer 3

Usually, forms of energy like this are either transformed into heat energy, or travel away from the Earth at the speed of light.

For signals transformed into heat, the information in that signal is destroyed even though energy is conserved. For signals that travel away from the Earth, you will never receive the signal again (here on Earth) unless somewhere out in space there is a reflector to redirect it back to us.

Answer 4

they seem to be a band it extremely is in no way totally capitalized on their skill, they are too busy attempting to sound British. Their stuff is hit or pass over. i like a number of their songs, like What Ever got here approximately To My Rock And Roll?

Answer 5

no, yar..... it is a form of energy but it is converted t that time only and the new signals after that overlaps them.... so we can get the signals of a minute before also.....
oki.....

Answer 6

drop a rock in a puddle .. and then talk to me same principle they dont stay here ..they bounce into space and get slower ..and weaker and yea...just like a rock in water
