Question

photo electic spectrometry​

Answer 1

Explanation:

Key points. Photoelectron spectroscopy (PES) is an experimental technique used to determine the relative energies of electrons in atoms and molecules.

The basic function of a spectrometer is to take in light, break it into its spectral components, digitize the signal as a function of wavelength, and read it out and display it through a computer. ... In most spectrometers, the divergent light is then collimated by a concave mirror and directed onto a grating.
