Which heat transfer mechanism is demonstrated by standing near a heater and feeling warmth without direct contact?

Explanation:
Radiation is heat transfer through electromagnetic waves, which can reach you without any contact or even a heated air path. When you stand near a heater, the heater emits infrared radiation that travels through the air and is absorbed by your skin, making you feel warm despite not touching the heater. This distinguishes it from conduction, which requires direct contact with the hot surface, and from convection, which relies on the movement of warm air to carry heat. Evaporation isn’t involved in this warming effect.
