The photon energies used in different types of medical x-ray imaging vary widely, depending upon the application. Single dental
x rays use photons with energies of about 25 {\rm keV}. The energies used for x-ray microtomography, a process that allows repeated imaging in single planes at varying depths within the sample, is 2.5 times greater. What are the wavelengths of the x rays used for these two purposes? answer in m
\lambda_{\rm dental}
\lambda_{\rm microtomography}
