What is often seen at detonation during the thermal effect of an explosion?
Correct Answer:
Fireball or bright flash of light
Explanation:
The thermal effect of an explosion is driven by the enormous heat and radiant energy released in a fraction of a second. This rapid heating creates a bright flash of light and a glowing fireball as the hot gases and surrounding materials radiate energy. Craters, debris clouds, and ground tremors come from the blast’s mechanical energy and subsequent fragmentation or ground movement, not from the heat radiation itself. So the fireball or bright flash of light is the hallmark seen during the thermal phase.
