Using electromagnetic waves to investigate radiation
Using electromagnetic waves to investigate radiation

Answer 1

The investigation that shows the transfer of heat energy in the absence of matter is:

Using electromagnetic waves to investigate radiation.

Radiation can occur without the need for a medium, as it transfers energy through electromagnetic waves.
