    Kinetic energy of the emmited electrons

    (1) The work function of a particular metal is 2.00 eV. (a) If the metal is illuminated with monochromatic light of wavelength 550 nm, what will be the maximum kinetic energy of the emmited electrons and, (b) their maximum speed? (c) What is the required stopping potential...

    Quantum Physics and photoelectrons

    here are another questions,I need someone to help me! (1)A metal work a work function of 2.40 eV is illuminated with a beam of monochromatic light.The stopping potential for the emmited electrons is 2.50 V.What is the wavelength of the light in nanometer? (2)What is the lowest frequency of...

    Quantum Physics(ionization Energy)

    I need help to do my assignment here, :confused: the ionization energy of a hydrogen atom is 13.6 eV.would the absorption of light of frequency 7.00x10^15 Hz cause a hydrogen atom to be ionized? :confused: calculate the wavelengths of all the radiations in Lyman series in the hydrogen...
