Try our simple thermography quiz Related 2 Comments Hi Bob – I got 13 out of 15 correct. (Would be great if there was a note to which answers are right/wrong) I may have answered the COLOUR question “incorrectly” – colour DOES have an influence on Emissivity, just not at the wavelength we usually work with. Black IS a better emitter/absorber of infrared (if you take the whole IR band into account) – Even if you go to the Mid Wave band – I believe you see a difference. Not sure which other one I got wrong. Reply Yes the other one I got caught out by the usual emissivity, absorbsivity reflectivity 0.7 – 0.3 Reply Leave a Reply Cancel replyYour email address will not be published.
