Infrared radiation is widely used in industry, scientific research, medicine and military technology. The book provides with a wide range of issues related to IR radiation. It is of interest two closely spaced glass plates exceeding Planck’s blackbody radiation law,Applied Physics Letters, Vol.
92. The spectrum of solar radiation important for environmental physics ranges from the ultra-violet to the infra-red. Wavebands used for vision, photosynthesis, and aspects of plant development (phytochrome absorption) are reviewed.
Solar radiation is scattered and absorbed in the atmosphere by molecules, cloud droplets, and particles (aerosol). Far infrared (FIR) is a region in the infrared spectrum of electromagnetic radiation. Far infrared is often defined as any radiation with a wavelength of 15 micrometers (μm) to 1 mm (corresponding to a range of about 20 THz to GHz), which places far infrared radiation within the CIE IR-B and IR-C bands.

Gamma radiation is a form of nuclear radiation produced by certain radioactive elements as they decay. In particular, gamma radiation is ionizing radiation, meaning that it is sufficiently energetic to break bonds in genetic material, structural components of cells and other biological molecules.
In physics, the term light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays, X-rays, microwaves and radio waves are also light. Like all types of EM radiation, visible light propagates as waves.
Radium and Radioactivity By Mme. Sklodowska Curie, Discoverer of Radium from Century Magazine (January ), pp. The discovery of the phenomena of radioactivity adds a new group to the great number of invisible radiations now known, and once more we are forced to recognize how limited is our direct perception of the world which surrounds us, and how numerous and varied may be the.
Electromagnetic radiation with a wavelength of over nm is called infra-red, and radiation under nm is ultra-violet. Each color on the spectrum can vary in saturation, lightness and darkness, and it's estimated that a human eye can distinguis about 10 million color variations.
