Title: (physics ques) Calculate the energy in electron volts of a photon having a wavelength in the following ranges? Post by: rjcool123 on Sep 6, 2012 (a) the microwave range, 5.90 cm
(b) the visible light range, 5.80 multiplied by 10-7 m (c) the X-ray range, 5.20 multiplied by 10-8 m please helppp! Title: (physics ques) Calculate the energy in electron volts of a photon having a wavelength in the following ranges? Post by: irina on Sep 6, 2012 It's just Plancks constant (4.135 × 10?15 eV/s) times the speed of light and divided by the wavelength.
