Radio messages are often transmitted better at night due to the lower levels of atmospheric noise and the ionospheric conditions. During the day, the sun's radiation ionizes the upper atmosphere, which can absorb and scatter radio waves. At night, the ionosphere becomes more stable and reflects radio waves more effectively, allowing for longer-range transmission and clearer signals. This phenomenon is particularly beneficial for medium and shortwave radio frequencies.

3 How is digital radio different than the types of radio that came before It?
The way the signal is transmitted and processed. FM radios are transmitted via signal generators and amplifiers on the ground while digital radio like Sirius or AM are transmitted via satellites. The digital signals are sent in packets vs. lower frequency radio waves.
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.
Where did Reginald Fessenden invent the radio?
He did some early experiments with radio in Canada, and he may have transmitted before Marconi in Italy.
What was the second record to be played on radio 1?
On Christmas Eve night, a Canadian inventor named Reginald Fessenden played. "Largo" by Handel using an alternator transmitter. He then transmitted himself playing, "O Holy Night" on the violin.
What is a radio controlled watch used for?
Radio controlled watches use radio waves that are set by synchronizing a time code that are transmitted by a radio transmitter. These radio controlled watches are used to set and display the time accurately.
How do you put transmitted in a sentence?
''The radio waves were transmitted from the the radio tower and were picked up by the radio itself'' Hope that helps!
When did you first transmit radio telegraph messages?
The first successful transmission of radio telegraph messages occurred in the late 19th century, with Guglielmo Marconi's experiments in 1895 laying the groundwork. By 1899, he successfully transmitted signals across the English Channel, demonstrating the potential of wireless communication. This marked a significant milestone in the development of radio technology.
What type of electromagnetic waves is used in texting?
Texting typically uses radio waves, specifically in the range of frequencies allocated for cellular communication. These radio waves are transmitted and received by mobile phones to exchange text messages.
What is a sentence with the word transmitted?
The data was transmitted via email. Disease can be transmitted from one person to another through contact with common objects such as a doorknob. The radio station transmitted a live rock concert on its station last night.
Is radio commercial input or output?
Radio commercials are considered output because they are a form of content produced and transmitted by radio stations to reach their audience. They serve as promotional messages designed to inform or persuade listeners about products, services, or events. In this context, the radio station outputs the commercial to its listeners as part of its programming.
Does air messages pollute the air?
If you mean "on air" as with radio and television, mobile telephones etc., then no they do not. They are part of the electromagnetic spectrum and are transmitted through this. I suppose you could say they pollute the electromagnetic spectrum.
Cell phone signals are transmitted by?
radio waves radiation
How spaceships send messages back to earth through the vacuum of space?
Space craft send messages electronically via radio waves. And these actually move through a vacuum better then through the atmosphere.
How can radio waves be transmitted over half the world?
The Earths ionosphere reflects low frequency radio waves. At night it moves higher up. You can literally aim your antenna at it and bounce a signal to a very far away location.
How is mobille phones signal transmitted?
Radio Waves

What part of the transmitted radio wave changes if you cahnge radio station?
Your radio separates the stations according to their frequency (wavelength).
