The energy of a photon with a wavelength of 0.07078 nm is calculated using the equation E = hc / λ, where h is Planck's constant (6.63 x 10-34 J·s) and c is the speed of light (3.0 x 108 m/s). The initial calculation yields an energy of 17563.2 eV, but the correct value is approximately 17520 eV. The discrepancy is attributed to the significant figures used in the calculations, highlighting the importance of precision in scientific computations.
