What is the difference between radio horizon and optical horizon?

radio signal bents around the curvature of earth and hence travel longer distance than the line of sight signal. At ultra high frequencies signal follows the line of sight path and hence maximum communication distance is limited due to curvature of earth for given height of transmitting and receiving antenna

How do radio telescope different from optical telescope?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
What is the difference between Radio detection and ranging and Radio detection and ranging satellite?
The Difference is that Radar Satellites are just a more advanced version of Radar.
How does the ionosphere help us?
The ionosphere has the useful property of reflecting radio waves, thereby enabling us to send radio signals past the horizon.
What is the difference between a weather forcaster and a meteorologist?
A meteorologist is someone who studies the weather patterns, while a weather forcaster is a man or woman on television or radio who tells the weather.
How do we see deep into space?
We see deep into space by using optical or radio telescopes, either from the Earth's surface, from satellites orbiting above us, or carried out into space on an unmanned spacecraft.
What is the difference between optical and radio?
Optical telescopes use either lens' (refractory) or mirrors (reflective) to magnify light. Radio telescopes use dishes to pick up radio waves. sensors on the dishes collect the waves and turn them into a picture
In what ways are radio telescopes better than optical telescopes?
Both types of telescope collect and focus electromagnetic radiation for observational purposes, the difference is their band of observed frequencies. Radio telescopes are used for the radio frequencies ( ~3km - ~30cm) while optical telescopes are used for frequencies closer to visible light ( ~0.7μm - ~0.4μm). Optical telescopes may also be able to detect infrared and ultraviolet light.
How radio telescopes differ from optical telescopes.?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
How do radio telescope different from optical telescope?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
How do radio telescope operate?
As far as I know, there is no "optical radio telescope". There are, separately, optical telescopes (which work with visible light), and radio telescopes (which work with radio waves).
What is the difference in a philips portable radio and a standard radio?
The difference between a Philips portable radio and a standard radio are that a Philips radio is battery powered, while a regular radio is electrically powered.
What effects did radio horizon?
Radio Horizon had many effects on the era that it was presented in. This was the first known radio station, and it greatly changed electronics and communication over time.
What is the difference between ultrasonic welding and radio frequency welding?
what is the difference between ultrasonic welding & radiographic welding
What is the difference between radioisotopes and radionuclide?
diff between radio isotope and radionuclei
What is the difference between radio nd optical telescopes?
Optical telescopes use either lens' (refractory) or mirrors (reflective) to magnify light. Radio telescopes use dishes to pick up radio waves. sensors on the dishes collect the waves and turn them into a picture
Do Radio telescopes have poorer angular resolution than optical telescopes because radio waves have a much longer wavelength than optical waves?
yes
Are optical telescopes much bigger then radio telescopes?
No they are not bigger then radio telescopes at all.
