The main scientific interest here from his point of view was the additional hard data it lent to the grand question of the mechanism by which molecules absorb radiant energy.With this setup Tyndall observed new chemical reactions produced by high frequency light waves acting on certain vapours.

This one, from Heat Considered as Mode of Motion, is his setup for demonstrating that air cools during the act of expanding in volume; and that air heats up during the act of compressing in volume.

About this person

John Tyndall (; 2 August 1820 - 4 December 1893) was an Irish physicist. His scientific fame arose in the 1850s from his study of diamagnetism. Later he made discoveries in the realms of infrared radiation and the physical properties of air, proving the connection between atmospheric CO2 and what is now known as the greenhouse effect in 1859.
