Question

Calculate the energy of a photon in kiloelectron volts (keV), which has a wavelength of 0.345 Å ? Significant figures are graded for this problem. Physical constants used to solve this problem should contain a minimum of four significant figures to avoid rounding errors. Be sure you do not round your answers until the very end of your calculations.

Answer 1

Explanation:

Calculate the energy of photon in kiloelectron volts (keV), which has a wavelength of 0.942 A. Note: Significant figures are graded, physical constants should maintain at least 4 sig figs to avoid rounding error. Don't round until the end of all calculations.
