A molecule of carbon dioxide traps heat, radiant heat, the long wave end of the spectrum.
The substances, how-r, which show themselves thus opaque to radiant heat perfectly transparent to light.
But, as you know, radiant heat can flash right through a vacuum.
The sun contains a certain store of energy, part of which is continually disappearing in the form of radiant heat.
This fact indicates that radiant heat travels in straight lines.
This screen wall, however, cuts off a large quantity of radiant heat.
The house is centrally heated with radiant heat from the floor.
This radiant heat, though obscure, exhibits a deportment exactly similar to light.
Now radiant heat, as we have seen, is such a lower grade of energy.
But the same divergence is to be observed between light and radiant heat, of which the action of glass is a familiar example.
