c.
All electromagnetic radiation travels at the same speed in a vacuum; it is labelled c.
They both travel at the same speed, the speed of light
Ultraviolet
All electromagnetic waves move at the same speed, at least in vacuum. X-rays and microwaves ... as well as radio, infrared, ultraviolet, heat, and visible light ... are all electromagnetic waves, and travel at the same speed.
Both infrared and ultraviolet are kinds of electromagnetic radiation, as is the visible light.
ultraviolet has more energy.
The speed of X-ray in vacuum is the same as the speed of radio, microwave, light, heat, infrared, and ultraviolet: 299,792,458 meters (186,282 miles) per second.
no

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.

They are the same.
Ultraviolet is higher frequency, then visible light, then infrared.
Right between infrared and ultraviolet. It has higher frequencies than infrared; lower frequencies than ultraviolet.
All travel at the same speed through a vacuum
