In a photoelectron spectroscopy experiment, photons with wavelength 130 nm cause the ejection of 6 s electrons from gold, but photons with wavelength 200 nm do not. A student claims this is because the photons with wavelength 200 nm are lower in energy than photons with wavelength 130 nm . Do you agree or disagree with the student's claim? Justify your answer in terms of the energies of the photons.

Explanation:

The energy of a photon refers to the energy carried by each photon. The energy of a photon is inversely related to its wavelength.

This simply means that the longer the wavelength of a photon, the lower the energy of the photon.

200nm is longer than 130nm, therefore, 130nm photon has more energy than 200nm photon.

This explains the fact that photons with wavelength 130 nm cause the ejection of 6 s electrons from gold, but photons with wavelength 200 nm do not.
