This educational illustration depicts thermal radiation, where a campfire emits infrared energy as electromagnetic waves, shown by curved arrows radiating outward in all directions. Unlike conduction or convection, radiation requires no medium and travels at light speed through vacuum. The glowing flame and wood logs emphasize real-world combustion and energy release.

Used in physics, thermodynamics, and environmental science educational materials to explain heat transfer mechanisms; ideal for textbook figures, online courses, or STEM outreach content targeting high school to undergraduate learners.
