It is because longer wavelength wave is diffracted by the earth's atmosphere and so can 'cling' to the surface of the earth, whereas shortwave just goes out into space.

What are not able to travel through empty space ultraviolet waves or sound waves?
Sound waves cannot travel through empty space because they require air particles to transfer them. UV is a light wavelength and can travel through space (just like light from the Sun reaches the planets).
Why radio waves cannot travel through water?
Radio waves do not travel well through water.Radio waves travel at the speed of light, and just like light, are absorbed by water, in the same way as the deeper you go the darker it gets. Ultra long radio waves travel the best in water, but even then only a few hundred metres. Radio,visible light, infrared, ultraviolet, x-rays, microwaves and various other kinds of waves turn out to all be the exact thing. The only difference between them is the "wavelength" of the wave. In any wave something moves back and forth and the length of one complete cycle is called the wavelength. It turns out that all of these waves are able to move charges around - sort of. The thing is that the radio and waves with longer wavelengths move charges better than visible light and x-rays. That's because the shorter the wavelength, the faster the charges have to move to keep up. And moving all those charges around sucks up a lot of energy from the wave. So, in fact, the saltier the water, the less able radio waves will be able to penetrate through it. By the way, using the same sort of reasoning you can explain why metals are not transparent :-P .
What is the frequency of sound waves with a wavelength of 60m traveling in air at a speed of 380 ms?
Frequency = (speed) / (wavelength) = 380/60 = 6-1/3 Hz. (You may be able to feel it, but you can't hear it.)
How far in nanometers is the wavelength of a 10000 Hz sine wave and how far for a 20000 Hz sine wave also?
Wavelength = (speed)/(frequency)For a 10,000 Hz wave:,Wavelength = (speed)/(10,000) metersThat's (speed) x 100,000 nanometers.,For a 20,000 Hz wave:,Having doubled the frequency, the wavelength has now been reduced by half.So wavelength is now (speed) x 50,000 nanometers.,Note: It's often nice to be able to work with sine waves, but when you're only talking about frequency and wavelength, the wave-shape doesn't matter.
How does a laser travel in a straight line?
Many think a laser travels in a straight line due to it being made of particles since particles travel in a straight line when not acted upon by a force. This is not why a laser is straight. A laser is actually a wave and waves are able to travel around corners. If you notice, ocean waves actually seem to bend around corners. Sound waves do the same thing so that you can hear someone in another room. Light waves can do the same thing. The reason they don't is because they are much smaller than the opening they pass through. Ocean and sound waves have a much longer wavelength than light does. If ocean waves passed into a harbor they would also travel in a straight line. When the wavelength is much smaller than the opening they pass through the interferance created by the corners of the opening, destroying all the waves that are not moving in the direction of the waves before they passed through the opening. Therefore, it is wave interference that causes it to be so straight.
What are sound waves when they are trapped or not able to travel any further?
transmitted
What are not able to travel through empty space ultraviolet waves or sound waves?
Sound waves cannot travel through empty space because they require air particles to transfer them. UV is a light wavelength and can travel through space (just like light from the Sun reaches the planets).
Im a south African citizen with a british passport and want to travel to austria Germany and Amsterdam can i do so on my british passport?
As a British Citizen you are able to travel freely within the boundaries of the EU, without requiring further visa's.
What is c in the wavelength formula?
c = the constant value for the speed of light, or 3.00x 108. If you use this numerical value in your wavelength formula, you will be able to solve correctly.

Why does television signals travel through a vacuum?
television signals are communication signals, which can either be radio or microwave signals. These are both part of the electromagnetic spectrum. In the spectrum all the different signal types have some similar properties, including being able to travel through a vacuum, usually because they have a strong enough frequency and wavelength, and they don't need to travel in particles but waves :)
How does heat travels from the sun to plant?
through out the sun beams and sun particles because the sun is so large they sun beams are able to travel further just like a torch

Is infrared radiation the same as radiation?
No, if you look at a chart of the electromagnetic spectrum, you will see that microwave radiation is a longer wavelength ( approx. 1x10^8 Hz to 1x10^11Hz). Infrared is a smaller wavelength - approx 1x10^13 to ^15. The smaller the wavelength, the more able it is to penetrate matter. Radio waves do not penetrate our body because they are so very large, on the flip side, x-rays are very very small wavelengths and therefore can pass through our body.
You will be able to travel though time?
no
Did anbody travel to Saturn?
that is impossible. no one is even able to travel to mars.wow
