When there is a surrounding material such as air, rock, or water, this radiation interacts with and rapidly heats it to an equilibrium temperature.

As a result, solar wind and cosmic radiation interacts directly with the Martian ionosphere.

The radiation interacted with the glazes she used, producing an unusual depth and patina.

This radiation then interacts with the matter inside the volume.

The radiation, free to fly unhindered across space, will never interact with matter again.

The radiation interacts with matter and thus accelerates it outwards.

Electromagnetic radiation interacts with matter in different ways in different parts of the spectrum.

The radiation interacts with the particle (perhaps absorption, perhaps pushed back without ever making contact).

The infrared radiation passes through the crystal and only interacts with the sample at the interface between the two materials.

We can ask: what happens as the incoming radiation interacts with the ambient field?
