How do very long radio waves reach stations beyond the curvature of the Earth?
Radio waves, like all forms of electro magnetic radiation are affected by gravity, so the Earth's mass helps to bend the radio waves to an extent. Beyond that, radio waves can be reflected naturally by atmospheric conditions, but generally, when a radio signal needs to be transmitted a significant distance, it is done by a series of radio towers in relay.AnswerThe condition is called 'skip'. The waves bounce off the ionisphere and back to earth way past the curvature.
How do very long radio waves reach stations beyond the curvation of the earth?
Very long radio waves (extremely low frequency) follow the curvature of the earth in a ground wave.Short wave radio waves reflect off the ionosphere and "skip". This is an entirely different effect in a different frequency band. However the two effects are sometimes confused.
Why do you think Lindbergh's flight line is not a straight line from Long Island to Paris?
Because it followed the curvature of the earth.
When a pilot flies a long distance flight - does the pilot have to descend the plane mid-flight to match the curvature of the Earth?
No. Level flight for an aircraft is not flight in a straight line (vertically) but one that follows the curvature of the earth. It is an arc that maintains the same altitude.
Why FM signal cannot be transmitted over long distance?
FM stations are assigned to a part of the VHF band. VHF only travels in straight lines. It cannot follow the earth's curvature or get past mountains. That limits the range. Its not FM thats the issue, but the assigned transmitter frequencies.
How long is it from us to Hong Kong?
based on calculations using google earth, that would be approximately 2,770 miles on a straight line on a plane area. however, this distance may increase if the curvature of the earth is taken into account. \ecsanchez
How International Space Station used in observing the earth?
the international space stations is somewhere in space and hence the name international space stations it is there for the whole world to use engineers and scientists stay out there for long term
How does the curvature of the Earth affect the time in the air and the range of a missile?
The force of the curvature of the Earth, along with gravity is known as the Coriolis effect. How this would effect any long range projectile (bullets, missiles, etc.) is that it will change the path of flight. Meaning, that gravity will slowly pull the projectile down onto the surface. While the downward pull isn't at dramatic as it is for the missile (due to its constant propulsion), the curvature of the earth is VERY important. This is because you have to take in the total distance the missile is to travel in order to his its intended target. The curvature of the Earth (if the target is far enough) will not only obstruct the line of sight (especially if the target is say in another country, or a few miles away), shooting straight would be out of the question. All this, due to the curvature, this, in turn, requires missiles to be shot up, and then come down onto the target in a pyramid shape... hope this helps... oh, and to actually answer your question. The curvature of the Earth changes the time of flight on a missile because it forces us to launch the missile upwards first, then downwards. The flight path of a missile is, therefore, increased.
When where roads invented?
Straight roads were invented in the pre-roman iron age. And did you know, that some roads in America go straight for such long distances that they have to make a right turn to account for the curvature of the earth so it conforms to the map?
What do astronamers study?
earth and space science is the study of earth and its place in the universe.some earth scientist study the forces that have shaped earth throughout its long history.others study earth's oceans or its weather.space scientist study the planets and stars that exist beyond earth.
Where should the bulb be placed in headlights if the beam of light have to travel long distance?
center of curvature C
