Radiant heat refers to heat energy that is transferred through electromagnetic waves, which allows it to travel through space without needing a physical medium like a solid or liquid. This form of heat transfer is responsible for warmth experienced from sources like the sun or a fire, even at a distance, since it does not require direct contact or conduction.

In the context of a fire, radiant heat can contribute significantly to the spread of fire and can ignite nearby combustible materials even if they are not in immediate contact with the flames. Understanding radiant heat is crucial for fire investigations since it helps to analyze how fires develop and spread, as well as the thermal exposure that structures and materials experience during an incident.

This understanding highlights why options related to conduction or heat only felt at close range do not appropriately describe radiant heat, as those concepts involve different mechanisms of heat transfer and distance limitations.
