Q11.19Short answer
Consider Fig.11.1 for photoemission. How would you reconcile with momentum-conservation? Note light light (photons) have momentum in a different direction than the emitted electrons. metal 11.20 Consider a metal exposed to light of wavelength 600 nm. The maximum energy of the electron doubles when light of wavelength 400 snm is used. Find the work function in eV. Fig. 11.1
