So to get accurate measurements do we have to manually change Emmisitivity settings for different materials? For general purposes its right to assume we want to gauge temperatures of different materials at once --- so how does it work?----> is it just a little off?

No explanation here. They key piece is the thermal radiation sensor, but mentioning it in a sentence doesn't explain anything about how the technology works.

So everything above 0 Kelvin emits infrared photons? Really? She are the photons from? Plz help
@svenvalbruak519710 жыл бұрын
faninish i agree with you, but doesn't the video say that the suns temperature results in it releasing most of its light energy in the infrared spectrum? the violet and onward side of the spectrum is higher energy, but is not what the suns peak output is, therefor the infrared area in Herschel's experiment is hottest? just speculating
@chrisgewirtz587510 жыл бұрын
The infared thermometer is the hottest because the materials used to measure heat in the thermometer absorb different wavelengths differently. Say the thermometer was made of mostly glass and a little bit of alcohol, like it said in the video, glass absorbs infared well, but glass doesn't absorb blue light well, even if there was more blue light. The information isn't contradictory, you only need to keep in mind the absorption of the thermometer. To address faninish's point, yes blue and violet light have higher energy, but again they aren't absorbed as well. This experiment of Herschel's was only important because it was the discovery of infared, though it erroneously gave a temperature to specific wavelengths.

It doesn't PRODUCE it. IR, UV, etc are ALREADY PRESENT in sunlight. The prism just SEPARATES them out

+Justin Bohner Thanks for saving me the time. I thought IR cams & thermal cams were different. His intro says otherwise, so I'm already confused & need to find a better source. Karma should reward you the 10 mins & 16 seconds you saved me, hehe. Use it well!

04:35 this is wrong. most of the atmosphere (99% of the dry) does not radiate - absorb or emit - IR radiation. This is a law, and is the key assumption to greenhouse theory.

Annoyed by how there's no mention about the not very well known difference between near infrared (The kind commonly used in night vision cameras) and thermal infrared. Instead you imply there's only one type of night vision.
