What type of heat transfer occurs through electromagnetic waves?

The type of heat transfer that occurs through electromagnetic waves is known as radiation. This process involves the emission, absorption, and propagation of energy in the form of electromagnetic waves, which can travel through a vacuum or a medium without requiring direct contact between objects.

Unlike conduction, which requires direct contact for heat transfer through molecular collisions, and convection, which depends on the movement of fluids to transfer heat, radiation can happen through empty space.

Induction, on the other hand, involves the heating of conductive materials through electromagnetic fields, primarily used in specific applications like induction cooking, but is not a form of heat transfer based solely on electromagnetic waves in the same sense that radiation is. Thus, radiation is the correct answer as it specifically refers to the transfer of heat via electromagnetic waves, such as the warmth felt from sunlight or a heat lamp.
