Question

1. which of the following best explains why a person standing near a campfire feels warmth on only one side of their body? convection currents in the air conduction through the ground radiation transferring electromagnetic waves thermal expansion of surrounding materials

Explanation:

Radiation is the transfer of heat energy in the form of electromagnetic waves. A camp - fire emits heat through radiation. The side of the person facing the camp - fire receives these electromagnetic waves and feels warm, while the other side doesn't. Convection currents would affect the air around the person more uniformly in some cases and not just one side. Conduction through the ground is not relevant as it doesn't explain the one - sided warmth. Thermal expansion of surrounding materials is not related to the one - sided warmth feeling.

Answer:

radiation transferring electromagnetic waves
