electromagnetic waves propagating through space

What is radio waves? electromagnetic waves propagating through space at the

at the speed of light
transferred through space energy emitted

from an electromagnetic oscillation generator
born at the change of the electric field
characterized by frequency, wavelength and power portable energy

Слайд 6 How apply radio waves
radio waves are emitted

How apply radio waves radio waves are emitted via an antenna

via an antenna

the transmission of long-wave broadcasting stations

can be taken at a distance of several thousand kilometers

medium wave stations are audible within a thousand kilometers.

The energy of the short waves dramatically decreases as the distance from the transmitter.

study of short and ultrashort waves showed that they quickly disappear when you go near the Ground. When the direction radiation upward short wave back

shorter than 1 cm are affected by fog, rain, clouds, strongly limiting the communication range.
