Light of three different wavelengths—325 nm, 455 nm, and 632 nm—is shined on a metal surface. the observations for each wavelength, labeled a, b, and c, is as follows:
observation a: no photoelectrons were observed.
observation b: photoelectrons with a kinetic energy of 155 kj/mol were observed
observation c: photoelectrons with a kinetic energy of 51 kj/mol were observed
which observation corresponds to which wavelength of light?

Will give ! what are the advantages and disadvantages of nuclear power? check all that apply. one advantage of nuclear energy is that it does not produce carbon dioxide emissions. storage of nuclear waste is a short-term problem associated with nuclear energy. the problem with uranium mining is that a large quantity of uranium must be extracted to meet energy needs because the energy release from uranium fission is so low. safe operation of a nuclear power plant can be jeopardized by a human mistake.
