Similarity . . . both are electromagnetic waves, same speed, same behavior, same physical properties
Difference . . . wavelength (or frequency, which is completely equivalent)
X-rays and radio waves are both forms of electromagnetic waves that travel at the speed of light, but they differ in wavelength, frequency, energy, and applications. X-rays have shorter wavelengths and higher energy, making them useful in medical imaging, whereas radio waves are used for communication and have much longer wavelengths. These differences enable a variety of technologies to function effectively.
