Question

EXPLAIN THE WORKING OF RADIO?

Answer 1

A radio works on account of the transmission of signals, by modulation of radiowaves. Radiowaves are actually electromagnetic waves of frequency range $5\times {10}^{5}Hzto{10}^{9}Hz$. These waves are produced by oscillating electric circuits having an inductor an capacitor. The electromagnetic waves of frequency range 88 MHz to 108 MHz form modulated radio band, which is used for commercial FM radio.
