Question

Which is Einstein’s photoelectric equation?

Options

• \[h\nu=K_{\max}-\phi_0\]

• \[h\nu=\phi_0K_{\max}\]

• \[h\nu=\phi_0-K_{\max}\]

• \[h\nu=\phi_0+K_{\max}\]

Answer 1

Einstein’s photoelectric equation is \[h\nu=\phi_0+K_{\max}\]. Photon energy supplies the work function, and the remainder is maximum kinetic energy.
