The radio before, now, and his future.

1. THE RADIOThe radio is a way to transmit information
or any kind of sound from one place to
another over a long distance. A machine
that sends radio signals is called
transmitter, while a machine that pick up
the information is called receiver
The radio works with something call it
electromagnetism waves; these waves
transmit music, conversation, pictures
and data invisibly through the air, often a
million miles. A lot of devices that we use
every day work with this waves. Things
like communication and navigation would
be impossible without electromagnetism
waves
The radio was discovered by
experimental work on the connection
between electricity and magnetism began
around 1820. This investigation
culminates in a theory of
electromagnetism waves developed by
James Maxwell, which predicted the
system of electromagnetism in 1873. As
the same time many people was
experimented with wireless connection.
The first systematic and unequivocal
transition of electromagnetism was
performed by Hertz in 1887.
In 1895 the radio was invented by
Gugliemo Marconi whose transmit Morse
code and he called the wireless
telegraph, known as the radio
Radio has transformed society. When
radio arrived in 19 century, few people
were communicated. With the radio
invention the mass medio changed the
people learn about occurred invents early
and faster, and people can express and
communicated ideas easily with other
people around the world
Radio today is completely different from
15 years ago. The rise of social media,
online networking and new technologies
has allowed people to create their own
content. This make that people around
the world doesn’t listen any more radio,
and in a future the radio will decrease
because people prefer listen to their own
mp3 music than radio.
