Most communication Satellites orbit in what is know as a geosynchronous orbit. Meaning that they move at the same speed as the Earth making them appear to be non moving. These orbits are at the altitude of 22,450 miles above the Earth. Very few satellites orbit as close as a few hundred kilometers of the Earth because the force of gravity would cause them to slow down and eventually fall from the orbit back to Earth. The application of Propagation would be determining how a radio signal will react and how it would effect it's characteristics over certain terrain like mountains for example.

What should be the position of the antenna with respect to the direction of the transmitted radio waves so that the properly tuned in radio gives the better reception?
The antenna should be parallel to the electrostatic field of the wave, and perpendicular to its magnetic field and to its direction of propagation.
What wave viabrates faster radio wave or microwaves?
Microwaves ARE radio waves, with frequencies above 3 GHz.
Is ultrasonic wave radio frequency?
ultrasonic wave is sound frequency
What is a radio wave?
Radio waves are electromagnetic waves. The radio waves have the longest wavelengths in the electromagnetic spectrum. A radio wave has a much longer wavelength than does visible light. We use radio waves extensively for communications.
Which wave represents visible light?
Visible light is a type of electromagnetic wave.
What is the different modes of the radio wave propagation?
Ground wave, sky wave and space wave propagation

Which kind of wave requires a medium for propagation?
A Sound wave, water wave, earth quake wave. Electromagnetic waves (radio, light, etc.) do not require a medium for propagation.
What are wave propagation?
Propagation of disturbance suffered by a particle in a medium is called wave propagation Wave Propagation is a term used to estimate the actions and characteristics of a wave of motion either in solids, liquids, gasses, or electrical radio type waves by the environment it is in and what factors affect those waves behaviors.
What is the space wave propagation frequency?
Space wave propagation frequency is nothing special, it is the same frequency of the wave in question, for example WLAN Wifi produces 5.2 GHz radio wave from your computer or from router, so that would be the the space wave propagation frequency in question

What is transversal waves?
Wave is a propagation of oscillations of some physical parameter (perturbation of pressure, mass density, electrical or magnetic fields...). If oscillations are perpendicular to the direction of propagation - the wave is transverse (for example - electromagnetic wave). If physical parameter oscillates along the propagation direction - the wave is longitudinal(Sound).
