Tedious and time consuming as the process might be, it should help get everyone on the same wavelength. At the very least, Scott notes, it will create a paper trail that might be useful later on "if you...

Hotter things hurl out relatively more light of higher frequency and higher energy (shorter wavelength), which means they give off more visible blue light (short wavelength) compared to red light (higher wavelength) and infrared red (the invisible form of red light that hot things give off)....
An ordinary light microscope uses photons of light, which are equivalent to waves with a wavelength of roughly 400–700 nanometers. That's fine for studying something like a human hair, which is about 100 times bigger (50,000–100,000 nanometers in diameter). But what about a bacteria ...
“193-nanometer wavelength UV lasers are also fairly standard. This means that carbenes could be naturally forming in places like space, where there is a lot of methanol and ultraviolet radiation. And further reactions of carbenes formed in space through this process could lead to biomolecules ...
What is the principle of reversibility of light? Use your knowledge of refraction to describe how you could use it to identify an unknown substance. How to calculate refractive index from wavelength? What happens when a wave is refracted?
