The air under a reading lamp is warmed.
Explanation:
Radiation refers to the transfer of heat through electromagnetic waves, without the need for a medium. In this scenario, the heat from the reading lamp is transferred to the air directly through radiation. The electromagnetic waves emitted by the lamp, such as infrared radiation, carry the heat energy and warm the air around it. This process does not involve the direct contact or movement of particles, unlike convection or conduction.
