Question

heat waves coming off of a campfire warm bobs face. which type of heat transfer is this an example of? radiation - transfer through waves convection - transfer through a fluid conduction - transfer through direct contact

Explanation:

Heat from a camp - fire warms Bob's face through electromagnetic waves. Radiation is the transfer of heat through waves. Convection involves heat transfer through a fluid (like air or water in motion), and conduction is heat transfer through direct contact. Since the heat from the camp - fire reaches Bob's face without direct contact and not through a moving fluid in a significant way here, it is radiation.

Answer:

Radiation - transfer through waves
