Heat transfer that takes place in the form of electromagnetic waves is known as:

Heat transfer that occurs in the form of electromagnetic waves is known as radiation. This process does not require a medium, allowing heat to travel through the vacuum of space. It is how energy from the sun reaches the Earth and how heat can be felt from a distance, such as standing near a campfire without being directly in the flames.

In contrast, convection involves the transfer of heat through fluids (liquids and gases) where warmer areas of a fluid rise and cooler areas sink, creating a circulation pattern. Conduction refers to heat transfer through direct contact between materials, typically occurring in solids. Direct flame contact means that the heat is transferred through the flames themselves rather than through radiation.

Understanding these different modes of heat transfer is essential for fire safety educators since they play a significant role in fire behavior and the design of effective fire prevention and safety strategies.
