and they are necessarily concerned with the manner in which radio waves are propagated around the earth's surface and to distances beyond the horizon. These and older students of the subject have ...

This is because the radio waves they generate exert pressure on ... his team at Georgia Tech in Atlanta built a specialised 275m-long antenna, designed to hop between different frequencies ...

Bit by bit, the physicists have filled the gaps in the electromagnetic spectrum, which runs from X rays at the short end, through light and heat, to miles-long radio waves at the other.

Observational studies are the best tool researchers have to investigate long-term health effects ... With this development comes the use of radio waves in different ways using different frequencies.

Sunlight contains an electromagnetic spectrum (special waves such as the kind in x-rays that travel through emptiness or a vacuum) of light that stretches from very short gamma rays to very long radio ...

Energy suppliers and other stakeholders have committed to working together to replace 800,000 Radio Teleswitch (RTS) meters ...
