SUMMARY
The relationship between wavelength (λ) and maximum kinetic energy (KE) of emitted electrons is defined by the photoelectric effect. When light of wavelength 0.5λ is used, the maximum kinetic energy of electrons is E. Using light of wavelength 0.25λ results in a maximum kinetic energy of 3E. This is due to the inverse proportionality of kinetic energy to wavelength, confirming that as wavelength decreases, kinetic energy increases significantly.
