The Electromagnetic Spectrum
In this Teaching Astronomy and Space video, from the Institute of Physics (IOP), Teachers TV and the Science and Technology Facilities Council (STFC), Tim O'Brien and astrophysicist Chris North explain how astronomers use radiation from across the electromagnetic spectrum. They demonstrate how Jodrell Bank and the Herschel Space Observatory use radio waves and infra-red to reveal the hidden secrets of the universe.
The video includes good illustrations of the detection of infrared radiation from common objects and how the use of infrared detection in astronomy gives details that would otherwise be obscured.
