Question

Which investigation would best show the transfer of heat energy without any type of matter as a medium?(1 point)
Responses

an investigation of radiation using electromagnetic waves
an investigation of radiation using electromagnetic waves

an investigation of radiation using a current within a fluid
an investigation of radiation using a current within a fluid

an investigation of conduction using collisions between particles
an investigation of conduction using collisions between particles

an investigation of conduction through movement of particles within a solid

Answer 1

The best investigation to show the transfer of heat energy without any type of matter as a medium is:

**an investigation of radiation using electromagnetic waves.**

Radiation transfers heat energy through electromagnetic waves and does not require a medium, unlike conduction and convection, which involve the transfer of heat through matter.
