What determines the wavelength in absorption?
When looking at absorption or reflectance spectra, say in the range of 400nm to 2500nm, you can see peaks (or dips) at certain wavelengths, that are characteristic for the material absorbing and ...

Absorption spectra Oxygen vs temperature
Whilst recently commissioning a spectroscopic Tunable diode laser "Oxygen Analyser" on a waste-to-energy plant, I wondered how the Analyser (which fires a narrow wavelength laser across the ...

Differenciation between wavelength and energy: Does a photons wave-length or energy determine its refraction and absorption?
I know that a photons wavelength and energy are coupled and that my question therefore could be quite ridiculous.
However, as a Biologist, I simply learned that refraction is determined by a photons ...

Why do atoms absorb photons at specific wavelengths and reflect photons at wavelengths other than the absorbed photons?
As we already know that the electron emits light photons when it travels from one orbit to another, and that causes this transition is the electron absorption of the incoming photon. But when the ...

From a spectrometer, how to determine unknown substance in water?
I created a spectrometer that produces nice clean wavelengths, I calibrated it using a fluorescent bulb.
from that I can create a graph from the data.
after which, I use the known position to of ...

Electronic transitions in potassium
Potassium atoms in the electronic ground state absorb laser light at 769.9, 766.5, 404.7, 404.4, 344.7 and 344.6 nm. Obviously, these absorption lines exist because an electron is excited from the ...

Standard green glass reflection and absorption rates by wavelength [duplicate]
Is there any exact data on reflection and absorption rates based on wavelength for the common green glass materials ?
I know the rate itself is dependent of the angle, the exact composition of the ...
