Question

what is the speed of xrays in vacuum

Answer 1

Speed of any electromagnetic wave in vacuum is approx,
$3 \times {10}^{8}$
metres/s

Answer 2

The speed of X-rays in vacuum is 3.0×$10^{8}$m/s.

Explanation:

• X-ray wavelengths range from about 5.0 nm to about 1.
• X-rays travel at the speed of light in a vacuum, 186,000 miles per second.
• X-rays have a very short wavelength compared to other electromagnetic waves.
• All electromagnetic waves such as X-rays, radio waves and UV waves can travel only through vacuum.
• X-rays are electromagnetic waves with a wavelength in the range of 0.01 to 10 nanometers, frequencies in the range of 30 petahertz to 30 exhertz (3×1016 Hz to 3×1019 Hz), and in the range of 100 eV to 100 keV. corresponding to the energy.
• They are shorter in wavelength than UV rays and longer than gamma rays.
