Practice question · True or false
Thermal radiation can transfer heat through a vacuum because it travels as electromagnetic waves.
Hints
- Ask which mechanisms require matter to be present.
- Electromagnetic waves need no medium at all.
Show the answer
True
Why
Radiation requires no medium; EM waves carry energy through empty space (e.g., solar radiation reaching Earth).
