Earth's Atmosphere And Radiation, Artwork
Photograph - Photograph
Earth's atmosphere and radiation. Computer artwork showing the differing absorbance of electromagnetic waves by the Earth's atmosphere. Low frequency microwaves and radio waves (4th and 5th from right), and mid-frequency visible light (5th, 6th, 7th and 8th from left) are able to reach the Earth's surface, although long-wave radio (1st, 2nd and 3rd from right) is blocked. The majority of infrared radiation (6th, 7th, 8th and 9th from right) is absorbed by water in the Earth's atmosphere, although some does reach the surface. High frequency wavelengths including X-rays and gamma rays (1st, 2nd and 3rd from left) are absorbed by the Earth's atmosphere and so do not reach Earth's surface.
