A photoelectric experiment is conducted by the sodium surface with the work function of 2.28 eV.
i) If the surface is illuminated with light having a wavelength of 410nm, determine the speed and kinetic energy of the emitted electron
ii) Is the electron relativistic?
iii) Determine the minimum frequency required to detect a photocurrent?
iv) Determine the maximum wavelength of light which can be employed to detect the photocurrent?
v) Determine the speed and kinetic energy of the emitted electron when the incident light is 700 nm on the similar sodium surface?
