Correct answer: B. 16-1000μm
- A. 0.8-2.5μm
- B. 16-1000μm
- C. 2.5-16μm
- D. 400-800μm
Explanation
Here are the approximate wavelength ranges for different portions of the infrared region:Near-infrared (NIR): 0.75 μm to 1.5 μmShort-wavelength infrared (SWIR): 1.5 μm to 3 μmMid-wavelength infrared (MWIR): 3 μm to 8 μmLong-wavelength infrared (LWIR): 8 μm to 15 μmFar-infrared (FIR): 15 μm to 1000 μm (or 1 mm)

About Spectroscopy and Analysis
Spectroscopy studies how substances absorb, emit or interact with electromagnetic radiation. Coverage includes ultraviolet-visible absorption, infrared identification of functional groups, Beer-Lambert law, spectral interpretation and the use of spectroscopic data to identify or determine the concentration of chemical substances.
