X-rays have electromagnetic energy. The velocity of this energy travels at a speed of:

X-rays are a form of electromagnetic radiation, much like visible light, radio waves, and gamma rays. All forms of electromagnetic energy travel at the same speed in a vacuum, which is approximately 300,000 kilometers per second or about 186,000 miles per second. This constant speed of light is a fundamental principle in physics and applies universally across the electromagnetic spectrum, including when discussing X-rays.

Understanding this speed is critical in fields such as radiology and medical imaging, as it affects how we calculate the time it takes for X-ray beams to travel from the source to the imaging receptor. Such knowledge is essential for ensuring accurate imaging and proper operation of X-ray machinery.
