The investigation that would best show the transfer of heat energy without any type of matter as a medium is "an investigation of radiation using electromagnetic waves."
The investigation that would best show the transfer of heat energy without any type of matter as a medium is "an investigation of radiation using electromagnetic waves."
Explanation:
Heat transfer can occur through three different methods: conduction, convection, and radiation. Conduction involves the transfer of heat energy through collisions between particles in a solid or a stationary fluid. Convection involves the transfer of heat energy through the movement of particles within a fluid. Radiation, on the other hand, is the transfer of heat energy through electromagnetic waves, and it does not require any medium to transfer the heat.
In the given options, the investigation of radiation using electromagnetic waves is the only one that explicitly mentions the use of electromagnetic waves. Electromagnetic waves are capable of transferring heat energy without the need for any matter as a medium. This investigation would involve studying how heat energy is transferred through waves of radiation, such as infrared radiation or visible light.
Therefore, the correct answer is "an investigation of radiation using electromagnetic waves."
