Question

X-rays are electromagnetic radiation whose wavelengths are of the order of ________________.

• A. 1 meter
• B. ${10}^{-1}$ meter
• C. ${10}^{-5}$ meter
• D. ${10}^{-10}$ meter

Answer 1

The correct option is D ${10}^{-10}$ meter

X-rays are a form of electromagnetic radiation. They have a wavelength ranging from ${10}^{-11}$ to ${10}^{-8}$ meters, corresponding to frequencies in the range 30 petahertz to 30 exahertz and energies in the range 100 eV to 100 keV. They are most commonly used for medical imaging.
