Document Summary
C = 3. 00*10^ 8 m/sec speed of light. Electrons are not ejected from the metal for frequencies of light lower than the characteristic frequency, v 0 , for that material, regardless of the intensity of the light. Kinetic energy of ejected electrons increases linearly with increasing v for v > v 0. Linear relationship kinetic energy & frequency. Einstein proposed (1906) that light is a particle photons bonded) Ionization energy energy required to remove first electrons (most weakly. K = kinetic energy of ejected electrons.
