In his explanation of the threshold frequency in the photoelectric field, Einstein reasoned that the absorbed photon must have the minimum energy required to dislodge an electron from the metal surface. This energy is called the work function (φ) of that metal. What is the longest wavelength of radiation (in nm) that could cause the photoelectric effect in W, where φ = 4.60 × 10−19 J?

D. is the answer hope that you

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
