No as they are both electromagnetic waves so have the same velocity but have differing wavelengths and frequencies.
Neither is nesesarily longer a wave can go on forever. Visible light is more reflective than infared light so it will last longer. If you are talking about wavelength, infared lights wavelength is longer.
Sound is effected by air pressure and temperature and the movement of the source. Light and radio waves are virtually unaffected by the air.
Light waves do diffract, but the effect is very very small. In general diffraction effects are important when the object interacting with the wave has dimensions that are comparable to the wavelength of the wave. Light waves have much shorter wavelength compared to the radio waves. Hence the effect. (It should also be noted that radio waves penetrate buildings much better than light waves, but that leads to a more nuanced discussion of diffraction effects.)
Our eyes cannot sense radio waves. Although radio waves, visible light waves, X-rays and gamme rays are all part of the Electromagnetic Spectrum, our eyes are only equipped to detect the part of the spectrum known as visible light.
Ultraviolet light, x-rays, and gamma rays are all electromagnetic waves that are more energetic than visible light.
The wavelength of radio waves are on the magnitude of 10^4 meters, while gamma rays have a far shorter wavelength of around 10^-14. This implies that gamma rays carry a lot more energy than radio waves, due to their frequency being much higher than that of radio wave frequencies.
Radio waves will disturb matter which is more or less on the order of magnitude of the wavelength of the waves.
Radio waves Radio waves are electromagnetic waves occurring on the radio frequency portion of theelectromagnetic spectrum.Discovery and utilizationRadio waves were first predicted by mathematical work done in 1865 by James Clerk Maxwell. Maxwell noticed wavelike properties of light and similarities in electrical and magnetic observations. He then proposed equations, that described light waves and radio waves as waves of electromagnetism that travel in space. In 1887, Heinrich Hertzdemonstrated the reality of Maxwell's electromagnetic waves by experimentally generating radio waves in his laboratory. Many inventions followed, making practical the use of radio waves to transfer information through space. Nikola Tesla and Guglielmo Marconi are credited with inventing systems to allow radio waves to be used for communication.For more information go to:http:/en.wikipedia.org/wiki/Radio_waves
Radio waves are longer than X-rays and because energy is inversely proportional to wavelength, X-Rays have more energy. The formula is 1.25uevm/wavelength, that is the energy is 1.25 micro electron volt divided by the wavelength in meters.
Gamma radiation is the only one, except for radio, heat, visible light, and ultraviolet light.
Sadly radio transmission "electromagnetic waves with frequencies below those of visible light" making it impossible to see :( For more info check: en.wikipedia.org/wiki/Radio
It hasn't been done and there is a problem because the background noise would prevent the use of radio communication over more than about 1 light year's distance. Radio waves travel at the speed of light, so it would take 2 years to get a message there and back from 1 light-year away.
