How mobile radio works with such a small antenna ?
As we know we must have an antenna of length 1/4th of our signal wavelength.So i checked my mobile and note down the frequency and after calculation i got result 1/4m(approx).But no any antenna of 1/4m i have in my mobile then how it works ?
Even i cut my earphone wires only plug is there which is of 1/10m but still it works and i can hear the sound clearly !!😕

No you are wrong NM,narayana murthyas per my knowledge we found a small piece which changes channels with the ear phones that is called as modem of the device to get that radio frequency
Try to simple insert 3mm jack which is connected with Speaker only then also you are able to catch the Radio Signals, the modem which you are talking is just interfaced with mobile phone controller and whenever you pressed that it will simply tuned to next channel but i have tried that without that Small box(modem) we are able to tune the Radio. 😀 -
