\nX-rays are a form of electromagnetic radiation with wavelengths ranging approximately from 10 picometers ($10^{-11}$ m) to 10 nanometers ($10^{-8}$ m). The option $10^{-10}$ metre falls squarely within this range.
\n<\/section>\n
\nX-rays occupy a position in the electromagnetic spectrum between ultraviolet radiation and gamma rays, characterized by wavelengths in the range of approximately $10^{-11}$ m to $10^{-8}$ m.
\n<\/section>\n
\nThe electromagnetic spectrum spans a wide range of wavelengths and frequencies. Radio waves have wavelengths of metres to kilometres. Microwaves are around centimetres to metres. Infrared radiation is roughly from $7 \\times 10^{-7}$ m to $10^{-3}$ m. Visible light is from $4 \\times 10^{-7}$ m (violet) to $7 \\times 10^{-7}$ m (red). Ultraviolet radiation is from $10^{-8}$ m to $4 \\times 10^{-7}$ m. X-rays are from $10^{-11}$ m to $10^{-8}$ m. Gamma rays have wavelengths less than $10^{-12}$ m.
