Yes, radio waves can travel long distances by bouncing off the ionosphere or using repeater stations. However, they can also travel short distances by line of sight without bouncing or repeating.

What type of waves are used to carry signals?

Electromagnetic waves are commonly used to carry signals in telecommunications, such as radio waves, microwaves, and light waves. These waves can travel long distances and carry information encoded in their frequency, amplitude, or phase.


Why are short-waves used in long distance broadcasrs?

Long-distance radio waves are particularly affected by the E and F layers of Earth's ionosphere, causing them to be refracted and reflected back to Earth at a much farther distance or range than they would travel along the Earth's surface. The Earth's surface often reflects the radio waves back up to the ionosphere, where they are again refracted and reflected back to Earth, adding another large distance to their range


What are three things radio waves can do?

Here are a few things that radio waves can do: 1. Communications (TV, Commercial radio, Ham radio etc.) 2. Heat things up, (Microwaves are just extremely short radio waves) 3. They can travel extremely fast (At the speed of light)


Which em waves are used in wireless technology?

Radio-waves are used in wireless technologies to transmit data between devices over a short distance.


What type of medium is required by radio waves?

radio waves do not require a medium to travel,it can even travel through vaccum

What is the main characteristic of sound?

Sound waves travel at great distances in a very short time. But as the distance increases the waves tend to spread out.


What is the objective of travel faster radio waves or sound waves?

sound waves


Why is there a time delay in receiving radio transmissions in the UK from Australia?

There is time delay because the radiotransmissionsare not instant; they may travel at the speed of light but that is notinstantaneous. Also, the radio waves have to travel up to asatellite, as the waves cannot go through the Earth.


How long does it take radio waves to travel from earth to Jupiter?

The distance between Earth and Jupiter can be anywhere between roughly 391 and 577 million miles, depending on where each of them is in its orbit. The corresponding transit times for radio (or light, heat, etc.) are: 390.8 million miles . . . 35 minutes 576.8 million miles . . . 51.6 minutes


Helps radio waves to travel great distance especially at night?

It depends on the wavelength. Some travel further during the day and others at night. It mostly has to do with the presence or absence of the sun and the ionosphere. At night the characteristics of the ionoshpere help bounce shorter wavelengths, like those of AM radio and short-wave radio bands, and some can even circle the Earth.
