It isn't. The velocity of both is the same at about 2.998x108m/s. A change in wavelength is associated with a change in frequency not velocity. The frequency of Ultraviolet light is about 750 PHz (Peta Hertz) while that of infrared half that at 375PHz.
Infrared waves have lower frequency and longer wavelengths than X-rays. They are both transverse waves, travel at the same speed in vacuum (3 x 108 ms-1) and do not require a material medium for their transmission. Infrared is non-ionizing, x-rays are ionizing.
You know its speed in vacuum, and frequency = (speed) / (wavelength) .

Infrared radiation is when earths surface radiates some of earths surface back into the atmosphereinfrared radiation is a type of electromagnetic radiation, which involves waves rather than particles. This means that unlike conduction and convection radiation can even pass through the vacuum of space.infrared radiation is a form of electromagnetic radiation which is emitted in the form of heat. infrared radiation is invisible
You need to divide the speed of light (in m/s) by the frequency (in Hz, which is equal to 1/s) to get the wavelength (in meters).

around 750 nanometers.
Vacuum wavelength is the wavelength that is measured if the wave is passing through a vacuum. To get the wavelength in a medium you need to know the refractive index.
Neither. In vacuum, all electromagnetic radiation has the same speed, regardless of wavelength. It's the speed we call "the speed of light", but it applies to all of those other electromagnetic phenomena too.

No, in a vacuum infrared radiation has a wave length of between 10^-6 and 10^-2 while radio waves have 10^-1 and beyond and long radio waves have a length of 10^3 and beyond.
Yes, infrared waves are part of the electromagnetic radiation spectrum and all electromagnetic radiation will propagate through a vacuum.

c.All electromagnetic radiation travels at the same speed in a vacuum; it is labelled c.
It can travel across the vacuum of space.
Lithium does indeed conduct heat. All forms of matter conduct heat to a greater or lesser degree; only a vacuum has no heat conducting capacity. And even in a vacuum, heat can be radiated in the form of infrared radiation.
The wavelength of a violet ray in vacuum is 400nm. The refractive index of diamond is about 2.42. Using the formula λ'=λ/n where λ' is the wavelength of the ray in a material, λ is the wavelength in vacuum and n is the refractive index of the material, we get λ'=165nm.
