John Tyndall (August 20, 1820 - December 4, 1893) Contribution to Sciece
John Tyndall was an Irish physicist that has contributed to the growth and development of science. He contributed to the fields of radiation magnetism and mountaineering. Tyndall was best known for his work on the scattering of light by atmospheric particles and gas absorption of infrared radiation. -
John Tyndall / Sound Phenomena
Tyndall's work on navigational aids leads to his interest in sound phenomena, which lead to him writing a book on sound (Scientific Biography). The book was written to appeal to both people of scientific culture and those of non-scientific culture on the science of acoustics (Scientific Biography). -
John Tyndall / The Tyndall Effect
Tyndall explains why the sky was blue and the color of the sun on the horizon. This was done with the use of his scattering of light particles in the atmosphere known as the Tyndall Effect (Scientific Biography). This was tested by Tyndal with the use of a tube, white light to depict the sun and smoke which was used to place into the tube. This made the beam of light look bluish when observing from the outside of the tube and reddish from the opposite end to the light (Conocimiento, et al). -
John Tyndall / Progression of Scientific work
Tyndall's work observes a steady progression within physics. His work on scattering of light particles in the atmosphere led him to the means of destroying airborne organic matter by heat (Scientific Biography). The hallmark of his genius was seen as his work on the movement of electromagnetism through thermodynamics into bacteriology (Scientific Biography). Video on Tyndall's Effect
