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