Light always travels at the speed of light.
The only time that's 299,792,458 meters per second ( " c " )
is when it's traveling in vacuum.

Radio waves, microwaves, infrared, visible light, ultra violet, XRays, and gamma rays are all part of the "electromagnetic spectrum". They are all electromagnetic radiation and they all travel at the speed of light (186,000 miles per second). The only difference between them is their frequencies (or wavelengths)
Radio waves are sound. Therefore, yes, by definition, they travel at the speed of sound.
It depends on the medium it is travelling though. In the vacuum of space, they travel at the same speed (c, the speed of light in vacuum). In air or water, the X-rays tend to just "rip" through the air at c... and get absorbed. Radio waves tend to propagate through the air at less than c, and keep on moving for long distances. Water tends to dampen and absorb both waves after just a few tens of meters (much less for x-rays) of travel path. It is not always the same event that triggers both x-ray and radio wave emissions. The processes generating both are sometimes offset in time. As a simile, the flash of lightning actually preceeds the bang of thunder, the neutrons from a supernova are emitted before the first detectable flare of a star shedding matter, and so on.
both the radio waves and infrared waves travels at the same speed but different in their frequency and wavelengthRadio waves:In radio waves wavelength is large(1 to 100km) and frequency is smallRadio waves are less energetic than infrared wavesInfrared waves:In infrared waves wavelength is small (0.7-30 micrometer) and frequency is largeInfrared waves are more energetic than radio waves
Radio waves do not emit visible light. Only light with wavelengths of roughly 4*10^-7 to 7*10^-7 meters are visible.
They never do.
Light waves ALWAYS travel at the "Speed of Light"....based on the medium that the waves are traveling through. It just so happens that they go the FASTEST in a VACUUM.

When it is moving through a vacuum.

You don't. The only objects that can travel at the speed of light are those that ONLY travel at that speed, like photons or gravitons.
Light waves always travel at the speed of light ... whatever it may be inside the material they're traveling through. They only travel at 300,000 kilometers (186,282 miles) per second in vacuum.

The speed of light in water is less than the speed of light in space. Only light can travel at the speed of light.
Only with a really light surfboard.
No, only surface and mechanical waves need a medium, compressional waves can travel through space. (Such as light from the Sun).I think light (EM) waves are the only ones that can travel through a vacuum. Sound waves require a medium.
Light waves and electromagnetic waves can travel through empty space. Water waves can only travel through matter. Hope this helped!
