A dental x-ray typically affects 175 g of tissue and delivers about 4.25 μJ of energy using x-rays that have wavelengths of 0.0255 nm. What is the energy (in electron volts) of a single photon of these x-rays?

For Reference: Speed of light c = 3 × 108 m/s Planck\'s Constant h = 6.626 × 10-34 J s Electron Volt (eV) 1 eV = 1.602 × 10-19 J

How many photons are absorbed during the dental x-ray?

    A dental X-ray for imaging impacted wisdom teeth produces an effective dose of 10 μSv. If a dental X-ray machine emits X-rays with an energy of 6.00x10–17 J each, how many of these X-rays must be absorbed per kilogram of tissue to produce an effective dose of 10 μSv? Assume the RBE of these X-rays is 1.00. X-rays/kg

    Quantized and total photon energy The particle characteristics of electromagnetic radiation are responsible for the quantized behavior of light energy. This behavior explains the results of varying the intensity and wavelength for an observed photoelectric effect, which describes the emission of electrons when light shines on a metal surface. If light only exhibited a purely wavelike behavior, then either increasing the intensity or decreasing the wavelength would both increase the rate at which electron are emitted. However, monochromatic light of...
