Today we showed various objects under the infrared camera, and discussed how an object’s emissivity impacts the absorption and emission of thermal radiation. But, an object which absorbs well in the visible spectrum—something that appears black—doesn’t seem to emit well in the visible—after all, it appears black. Therefore, knowing which parts of our experience to use to decide on an object’s emissivity is a bit subtle.

We began looking at thermal radiation during class today, and there are lots of great demonstrations and resources based around this topic. But, between the youtube video, the infrared camera, the kettle, the nail burning demo, the doc cam, my computer, two projectors, and the clicker, I had many balls to juggle during class today. Therefore, I wasn’t so smooth in all the transitions.

Therefore, I shared with my class that they made a JT-approved choice to be there in the morning.
