In 1873 there was a man named James Clerk Maxwell. He was a mathematician. He proved that electromagnetic waves could pass through air.
-
he studied electricty. he worked with thomas edison and worked on how exactly the waves worked.
-
In 1888 he determined that Maxwell's theory was correct. he demonstrated that the electromagnetic waves moved through the air. he did this by using radiation.
-
in 1892 the genius Nikola Tesla used maxwell's findings to demonstrate how it could be received and transmitted between two points. he decided that this could be a possible way to transmit sounds. He then went on to specialize in signal related things.
-
This was the first man to make a radio / wireless transmitter. It was capable of sending signals 1 mile away.
-
It was the first real radio. many were sold however they had many problems. they had their issues fixed, however there was still electrical issues and such.
-
He was the man to create crystal radio sets. he used maxwell's theory to make crystal radio. he used the base of the other kind of radios to make his.
-
The frist ever radio broadcast was in 1903. It was caalled o holy night
-
These replaced the spark gap radios.First widley used radios. They were common in households.
-
This man created fm radio. fm radio had a wider range and could go through buildings. It was the new kind of radio wave
-
This was created by Edwin armstrong. it wasnt blocked bty buildings. It also had a larger range than the other radio wave. it is commonly used today.
-
They were cheaper and more efficient. they widely were used after crystal radios. they were also smaller
-
Slowly after mp3 players started to come into play more often people have started to use the radiuo less and less therefor it is starting to die out.,
-
the song uptown funk was the biggest "hit' song ever recorded.
-
the current newest song on radio is Kings and queens
