In Einstein's photoelectric experiment, the kinetic energy of an electron displaced from a metal by a photon was the difference between the energy of a photon and a threshold energy value for the metal. If you were to perform a similar experiment with cobalt, which has a threshold energy of 8.01 x 10-¹⁹ J, and ultraviolet light of wavelength 41.3 nm, what would be the kinetic energy (in J) of the electron displaced?

Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
Question
Transcribed Image Text:In Einstein's photoelectric experiment, the
kinetic energy of an electron displaced from
a metal by a photon was the difference
between the energy of a photon and a
threshold energy value for the metal. If you
