You hear 'static'. Audibly - it's presented as a 'hiss'. It's believed to be the echo left over from the 'big bang' that created the universe.
Then your radio probably isn't grounded properly.
A guitar should be tuned to standard tuning, which is EADGBE, in order to play it properly.
Did you hear “ send me a superhero” on the radio?
cosmic background radiation :) This phenomenon can be picked up by an ordinary radio or tv. If your radio is not tuned into a station, then some of the the noise (interference) you hear is the cosmic background radiation caused by the Big Bang.
A ukulele should be tuned to the notes G-C-E-A in order to play it properly.
The antenna should be parallel to the electrostatic field of the wave, and perpendicular to its magnetic field and to its direction of propagation.
A signal from a radio station is tuned in a radio receiver by applying the signal to a resonant tuned circuit that accepts the wanted signal while rejecting all the other signals arriving.
Because their hearing apparatus (ear) is not tuned to hear ultrasound.
The only way your radio has of separating one station out of the pile, and letting you listen to the one single station you want to hear, is by frequency. If two stations are on the same frequency, then your radio hears them both when it's tuned to that frequency. If there are 100 of them, you hear all 100. The result of that is . . . well, just listen to CB some time.
To program the radio, you will need to manually tune in to whatever station you'd like programmed. Once tuned in to that station, press and hold one of the numbered preset buttons on your radio for several seconds. When you hear a beep, or a pause in the radio sound, it has been programmed. Repeat this process for each preset button.
Yes.Added: Absolutely - Your ordinary (consumer-type) cellphone is simply nothing more than a radio transmitter. Anyone tuned to the proper radio frequency can hear your conversation.
