X-rays travel at the same speed as visible light. All frequencies of electro-magnetic radiation (of which light is a very narrow band) travel at the speed of light (C) in a vacuum: 299,792,458 meters per second.
The speed of light varies in different medium. Given an angle of incidence other than 90 or 0, the wave will shift direction an amount determined by its frequency. The higher the frequency, the greater the shift. The transition between two medium of different refractive indices causes a variation in the phase velocity of the wave, but does not affect its frequency.
In a vacuum, all types of electro-magnetic radiation -- including visible light and x-rays -- travel at the same speed.
Things change when EM radiation travels through matter. Then its speed changes, but the change depends greatly on the type of matter being travelled through, and the frequency of the EM radiation.
No. X-rays are the exact same physical phenomenon as light,
only with a shorter wavelength. Their speeds are the same.
They travel much, much faster than that.

The amount of xrays produced in a photoelectric effect varies. . . . alot.
yes
Particles
They travel much, much faster than that.
Yes, all xrays travel at the speed of light.
No. We call it the "speed of light", but it's also the speed of radio, X-rays, heat, ultraviolet, microwave, gamma rays, etc, and all forms of electromagnetic radiation travel at the same speed, as long as they're in the same medium (vacuum or material substance).
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)

No. We would be unable to detect it but you can detect black holes(by xrays and light emmitted from material they are sucking up). You would be unable to detect it because if the two were moving away at a combined speed greater than that of light then light from the star could never reach the earth.
The speed of electromagnetic radiation is a constant. Its value is exactly 299,792,458 metres per second (about 186,282 miles per second) in vacuum, somewhat slower in material media. To give you some kind of a feeling for that speed, it would be the equivalent of 7 1/2 times around the Earth in one second. The speed is the same for all electromagnetic radiation. Gamma rays are one form of it. Others include radio, microwave, visible light, ultraviolet, X-rays, etc.
they are electromagnetic. So they have an electromagnetic spectrum.
gamma rays, xrays, uv light, visible light, infra red, microwaves, radio waves
a grid is a device placed in front of the image receptor which only allows xrays to travel directly through from the tube and prevent xrays which have been "scattered" from passing through to the image. This gives a much clearer resulting image. Grids are generally only used on thicker body parts where scattered xrays are more of an issue
Xrays, gamma rays, microwaves, ultraviolet rays, radiowaves and infrared rays.
They experimented with xrays on the prisoners in the concentration camps. Mostly at Auschwitz.
