Answer to Question #325792 in Quantum Mechanics for Rics

Question #325792

What is the wavelength of EM radiation that ejects 2.00 -eV electrons from calcium metal, given that the binding energy is 2.71 eV? What type of EM radiation is this?

Expert's answer

"E-E_1=\\frac{hc}{\\lambda},"

"\\lambda=\\frac{hc}{E-E_1}=280~\u00c5."
