wavelength L = 4.55*10^-8 cm
= 0.455*10^-9 m
frequency f = c/L
= 3.00^8 m/s/0.455*10^-9 m
= 6.59*10^17 Hz
Wave number w = 1/L = 2.198*10^9 m^-1
Energy = h f = _______
= _______ eV
You finish it. You need the exercise more than I do.
Calculate the frequency in hertz and cm-1, as well as the energy in joules and electron volts of an x-ray photon with a wavelength of 4.55 angstroms.
