: 3 A Photon Of Wavelength 435 Nm Strikes A Metal Surface Leading To The Ejection Of An Electron Mass 9 11 X 10 31 Kg 1 (20.39 KiB) Viewed 78 times

3. A photon of wavelength 435 nm strikes a metal surface, leading to the ejection of an electron (mass = 9.11 x 10-31 kg) at velocity 2.33 x 105 m/s. What is the work function and threshold wavelength (in nm) of the metal?
