Radio is the transmission of signals by modulation

of electromagnetic waves with frequencies below

those of visible light.

Radio is based on wireless communication or

setellite communication.

In this era of technology due to need of wireless

communication, A national service was planned

and developed by the Prasar Bharati Broadcasting

Corporation of India.

The first license granted for transmitting a broadcast was given on February 23, 1922. The Radio Club of Calcutta was the first radio club to start functioning in Nov-1924

The Government run broadcasting set up was called the India State Broadcasting Service (ISBS) which is then turned into AIR (All India Radio) in 8 June 1936.

The introduction of the commercial channel ‘Vividh Bharti’ in 3 October 1957 increased the interest and popularity of radio.

Today AIR has a network of 232 broadcasting centres with 149 medium frequency (MW), 54 high frequency (SW) and 171 FM transmitters. The coverage is 91.79% of the area serving 99.14% of the people's.

Transmitting

A radio wave carries information signal; Signals are converted into electrical

signals. A carrier wave is then produced from the modulation. The wave is then

amplified, and sent to the antenna that then converts signal into an E.M. wave.Receiving

An antenna on receiving the signal send it to the

receiver this then converts the electrical signal

sends it to the amplifier either a

speaker/headphones jack this is then

converted

into a sound wave.

How radio electromagnetic waves are changed to Radio Waves -

• The sound wave is equivalent to a pressure wave.
