Answer 1

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.**

Radiation refers to the transfer of heat energy through electromagnetic waves, such as infrared radiation, which does not require a medium to travel through.
