Determine the energy, the frequency, and the momentum of an X-ray photon having a wavelength of 0.10 nm .

Step-by-step solution

Given wavelength = 0.10 nm = 10⁻¹⁰ m . The energy of the photon is given by E = hc . Using hc 1240 eV nm , E = 1240 eV nm 0.10 nm = 12400 eV = 12.4 keV . The frequency of the photon is given by = c . = 3 10^8 m s ⁻¹ 10⁻¹⁰ m = 3 10¹⁸ Hz . The momentum of the photon is given by p = h . p = 6.62 10⁻³⁴ J s 10⁻¹⁰ m = 6.62 10⁻²⁴ kg m s ⁻¹ .
