The Sodium Metal Has A Threshold Frequency Of \(4.40 × 10^{14}\) Hz.
How to connect the azure functions work for @ willvelida in this post, you will explain what the bindings are in c. Calculate (i) threshold frequency (ii) work function for sodium. The work function w for a given surface is defined by the difference =, where −e is the charge of an electron, ϕ is the electrostatic potential in the vacuum nearby the surface, and e f is the fermi level (electrochemical potential of electrons) inside the material.
