Hello all, I have a monochromatic laser peaking at 808 nm and some non-scattering sample. I want to measure the absorption with a spectrometer. I can use the Beer-Lambert law to do this, but since it is a monochromatic laser I have some doubts. I could do a weighted-average, taking into...

Hi all, I've been for quite a while trying to identify this formula. dV / V = β ΔT - κ Δp where β is the thermal coefficient of volume expansion and κ is the isothermal compressibility. I think it's related to thermodynamics applied to solids and I can understand relations between the...

My name is Alexandre and I'm a physics student. The reason I signed up is to learn and hopefully teach what I have learned. Cheers
