Radios
 Introduction

Near the end of the 19th century, it was discovered that an electric spark sent out electrical energy which traveled through the air without wires and could be detected at a distant point. This discovery lead to the invention of wireless telegraph and then radio. 

Now the same technology is being used to transmit radio signals as well as signals for television, wireless phones and wireless internet.
