Infrared Radiation Tapestries

Description: This scientific diagram shows a color spectrum with an extra band marked IR beyond the red, and three thermometers showing the temperature rising highest past the visible light, on a deep dark background. In 1800 William Herschel placed thermometers in the colors of a spectrum and found that the temperature was highest beyond the red end, where no light was visible. He had discovered infrared radiation. A gift idea for physicists, engineers and physics students, and a striking addition to a study, lab or office wall.

Description: The electromagnetic spectrum encompasses the full range of electromagnetic radiation, organized by wavelength or frequency. It includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays—each with unique properties and applications in communication, medicine, astronomy, and more. Despite their differences, all forms of electromagnetic radiation travel at the speed of light in a vacuum and consist of oscillating electric and magnetic fields.
