Question

What gets heated up due to thermal radiation?​

Answer 1

$\huge\bold{\underline{\red{\mathrm{AnSweR}}}}$

Thermal radiation consists of electromagnetic waves (mostly infrared waves and visible light) emitted by an object due to its temperature. This radiation carries energy which is converted to heat when it hits another object and is absorbed. In contrast, conduction involves the direct movement of heat through an object.

Answer 2

Explanation:

Thermal radiation is electromagnetic radiation generated by the thermal motion of particles in matter. All matter with a temperature greater than absolute zero emits thermal radiation. Particle motion results in charge-acceleration or dipole oscillation which produces electromagnetic radiation.
