to determine the wavelength of maximum absorption
Each colored complex has a different maximum of absorption.
To determine UV-absorption you need to use UV-light. And there's a defined wavelength for UV-light.
In the small intestine.
Each substance has known specific maximum of absorption. Comparing spectra substances can be identified.
At 1 926 cm(-1) in infrared.
Sunlight
it is the absorption maximum for formaldehyde...
It has a large surface area for maximum absorption.
