Which investigation shows the transfer of heat energy in the absence of matter?

Question

A. Using particles in space colliding to investigate conduction
B. Using a current through fluid to investigate radiation
C. Using particle movement through a solid to investigate conduction
D. Using electromagnetic waves to investigate radiation

Answer 1

The correct answer is:

D. Using electromagnetic waves to investigate radiation

This option indicates the transfer of heat energy (radiation) without the need for matter, as radiation can occur in a vacuum through electromagnetic waves such as infrared radiation.
