How to show presence of infrared rays in the electromagnetic spectrum?

Answers

Answered by Suvi446

In the near infrared (NIR) and the short-wave infrared (SWIR) spectrums, we measure the reflectivity of objects. Thus, using a specific lighting working in an active infrared spectrum, we can capture the rays reflected by the object and produce its reflectrogram.
