why high frequency signals travels farther low frequency signals?

Answer 1

I believe it's the other way around. Low freq signals travel farther. A good comparison is groundwave propagation employed by shortwave frequencies as opposed to the line-of sight propagation employed at microwaves. Groundwaves travel much farther (almost worldwide) as compared to microwaves that need repeaters and are susceptible to fading. Obviously microwaves have higher frequencies than shortwaves. So evidently, higher frequencies have shorter range.

Answer 2

Your question is insufficiently stated, but I will assume you're referring to radio waves. In radio work, we find that certain frequencies seem to travel farther than others, but this is due only to the fact that they travel near the earth. The surface of the earth is either reflective or absorptive of rf energy depending on the frequency range, and the same is true for the atmosphere at low and high altitudes. You'll have to be more specific to gain any further information. However, it should be noted that in the midst of space, all radio signals travel from their source in uniform spherical waves, with no loss, to infinity.

Answer 3

Holden is correct.

All electro magnetic radiation has the speed 3x10^8 m/s.

They are not absorbed by vacuum.

There is no limit either for distance or for time for in this radiation to travel in vacuum.

When traveling in a medium the radiations can be absorbed, scattered, reflected, refracted or dispersed by the medium.

Higher the frequency higher is the absorption.

Therefore high frequency radiations travel less distance than low frequency radiations because of absorption.

Holden has given examples of micro wave, short wave and long wave.

In visible region, red has low frequency than green,
Red can travel more distance than green in air containing dust and other particles.

Also think of the rays coming from sun. All the rays from the sun reach the earth. We do receive gamma rays which have the highest frequency as well as infra red rays whose frequencies are less than gamma rays.

Therefore think of the penetrating power of these radiations than the distance that these rays can travel.

X-rays have high frequency than visible rays. These penetrate most of the solids than visible light.

Answer 4

ok, i am assuming that you're talking about electromagnetic waves (not the sound wave).

Low frequency waves have high tendency to be diffracted when going through as ostacle, which means that it is harder for it to "pass" through these obstacles, not only it will lose energy upon passing them, eventually, it will not be even strong enough to pass through them.

However, high frequency waves have a high penetracity, which allows it to penetrate walls and obstacles (think about gama rays). These properties allow high frequency waves to travel further as compared to low frequency waves.

Hope this helps

Answer 5

high frequency is more potent when it comes to hertz...it's all about broadcast strength,

I just said what every one else said . sorry I didn't fill in the blanks.
