No. Both travel at exactly the same speed. The speed of light.

### Do xrays travel at the speed of sound?

They travel much, much faster than that.

### Can visible light travel faster in a vacuum than both xrays and radio waves?

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).

8 minutes

### Is the velocity of X-rays constant?

Yes, all xrays travel at the speed of light.

### What is the electro-magetic spectrum?

gamma rays, xrays, uv light, visible light, infra red, microwaves, radio waves

### Is thr part of the EM spectrum that consists of waves with frequencies higher than those of visible light and lower than those of xrays?

What you're really asking is whether we have a name for that band offrequencies. Happily, yes we do. That's the part we call "ultraviolet".

### Do xrays travel faster than the speed of light?

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.

### Astronomers think that the areas around black holes give off?

A. visible light B. Nebulas C. Helium or D. Xrays

### Why xrays dangerous and not radio waves?

Although radio waves, visible light and X-rays are all part of the electromagnetic spectrum, x-rays travel with a much higher energy at a very short wavelength and create ionizing radiation. When an x-ray passes through organic matter the denser matter will block some of the radiation and that radiation will be deposited in the matter creating some cell damage.

### Is the visible light spectrum between radar waves and xrays?

Yes, radar waves are radio waves and too long for the eye to see (off the red end of the visible spectrum) and X rays are too short to see (off the blue/violet end of the visible spectrum).

### Which waves have shorter wavelengths radio waves or xrays?

X-rays have shorter wavelengths than radio, heat, infra-red, visible light, and ultra-violet.

### Which has a higher frequency gamma rays or xrays?

Gamma rays have a higher frequency than X-rays. Gamma rays are the most energetic form of electromagnetic radiation in the electromagnetic spectrum, whereas X-rays have a lower frequency than gamma rays.
