Light of insufficient energy-no matter how intense (bright) -is unable to eject electrons from a material (the photoelectric effect). Explain what happens if the energy of the light is greater than required.

Homework Answers

Answer #1

Light of insufficient energy-no matter how intense (bright) -is unable to eject electrons from a material (the photoelectric effect).photoelectric effect takes place only if sufficient amount of energy of radiation is strikes on the surface of a metal.Ejection of electrons from the metal suface depends on the energy of radiation but not on the intensicity of radiation.

if the energy of the light is greater than required, then ejection of electrons will takes place and photoelectric effect will be observed.
