Electro-Magnetic Radiation Mega Chart

Reflection, refraction, diffraction, oh my! Dive into the wonderful world of electromagnetic radiation–i.e., the energy that travels through space in waves, like x-rays, microwaves and good old visible light.

radiationbiggerLawrence Livermore National Laboratory, a national security lab in California, put this poster produced in 1944 by the W.M. Welch Scientific Company up on the lab’sFlickr page recently. Apparently it was rescued from the back corner of an unused office. Who’d want to hide this piece of science history?

See a full-screen version here. If you want to get up close and personal with the illustrations (including a great little sketch of how you get a sunburn), there’s a really, really big version here.

Thanks to Laurens Naude for the link!
