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
What else can I help you with?
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.
What year was the non optical telescope invented?
The non-optical telescope, primarily radio telescopes, were invented in the 1930s. One of the first and most notable radio telescopes was built by Karl Guthe Jansky in 1931.
What two regions of the electromagnetic spectrum are best utilized by ground based astronomers?
Ground based astronomers utilize the optical and radio regions of the electromagnetic spectrum. Optical wavelengths provide high-resolution images of celestial objects, while radio wavelengths help study objects that emit radio waves, such as galaxies and pulsars. By combining observations from both regions, astronomers can gain a more complete understanding of the universe.
What signal can go through the ionosphere?
Radio waves can pass through the ionosphere. This enables long-distance communication, such as radio broadcasts or communication with satellites, to be transmitted over the horizon.
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.
Why does the radio-path horizon distance exceed the geometric horizon?
The radio-path horizon distance exceeds the geometric horizon because radio waves can bend or be refracted by the Earth's atmosphere, allowing them to travel further than what is possible in a straight line. This bending effect enables radio signals to reach beyond the line of sight, extending the distance they can cover compared to the straight-line geometric horizon.
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 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
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.
What are the differences between AM and FM radio?
The main difference between AM and FM radio is the dial-in number and the amount of static each receive. AM radio preceded FM radio, with FM becoming popular in the 1950s.
