They are reflected round the curve of the Earth off layers in the atmosphere which act as mirrors (the ionosphere).

Does frequency reduces when the waves travel over long distance?

High frequencies are more damped by air than the bass frequencies.


IF the frequency is maximum then the signal will far awy or near?

higher frequencies attenuate more the further distance they travel.


What is the plural of frequency?

The plural of frequency is frequencies. As in "radio waves travel on different frequencies".

Why ground wave communication cannot be used for long distance using high frequency?

Frequencies over 30 Mhz normally travel through the ionosphere, whereas frequencies under 30 Mhz will normally bounce off the ionosphere, and back to earth.


Why do low frequency waves travel longer distances?

High frequencies are more damped by air than low frequencies.


Why do higher sound frequencies travel better at night?

Because at night the sun goes down, which is a good thing for frequencies, because the sun is giving of radiation which is disrupting the frequencies. so at night nothing is disrupting the frequencies.


What speed can you travel with a Thule 1600 cartop carrier?

A person should be able to travel the posted speed limit with a Thule 1600 car top carrier. This is assuming the car top carrier is mounted to the car properly.


Do cells phones interfer with wireless microphones?

All communication systems use electromagentic waves which by the law of Superposition of Waves travel independently in any meadium and hence do not interfere but if the frequencies tend to match then the carrier waves with amplitude modulation are more affected and give poor quality sound at the receiving end than the frequency modulated carrier waves.


What is the distance travel divided by the time needed to travel that distance?

Speed Average speed- the total distance traveled divided by the time it takes to travel that distance Velocity is also the distance or displacement divided by the time


What are the advantages of larger radio frequencies over smaller ones?

easier to transmit, higher frequencies radiate better. there is more bandwidth available at higher frequencies. higher frequencies travel in straighter lines so are more directional, this may or may not be an advantage depending on what is needed


Does AM radio travel through the ionosphere?

Any Amplitude Modulated radio signal will penetrate the ionosphere if its carrier frequency is high enough. Signals in the commercial AM broadcast band, with frequencies between 530 and 1700 KHz, aren't high enough. Most of their energy reflects from the ionosphere.
