Final answer:
Radiation is the transfer of thermal energy via electromagnetic waves and does not require a medium to convey the energy. This is how we receive heat from the sun.
option d is the correct
Step-by-step explanation:
The type of thermal energy that uses electromagnetic waves to transfer energy is radiation. Unlike conduction and convection, which require a medium to transfer heat, radiation can transfer heat through the vacuum of space.
For example, the heat we receive from the sun is transferred through radiation, which is a process where energy is emitted in the form of electromagnetic waves.
These waves travel through space and once they reach an object, the energy is absorbed, increasing the object's temperature. Thus, the object does not have to be in direct contact with the source of heat to experience the transfer of thermal energy.
