From a therapeutic viewpoint, what is the difference between heating by conversion, and heating by radiation?
a) Conversion involves direct contact with a heat source, while radiation relies on electromagnetic waves.
b) Radiation requires a medium for heat transfer, while conversion occurs without a medium.
c) Conversion primarily affects superficial tissues, while radiation penetrates deeper into tissues.
d) Radiation is more efficient at heating large body areas, while conversion is more localized.
e) Conversion is passive heating, while radiation is active heating.
