How to determine the conduction band edge of a heterostructure catalyst like TiO2 given the overal band gap and the valence band edge potentials?

I want to calculate the conduction band edge of my TiO2 sample having three phases making a heterostructure. I have got the band gap (nearly 3 eV) from UV-Vis spectroscopic analysis. I also have...

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...
