Heat energy can be transferred via electromagnetic waves.
yes
no, its radiation
Radiation!
A fireplace heats a room by radiation. That radiation is the direct transfer of energy by electromagnetic waves.
what is the transfer of thermal energy by radiation
what is the transfer of thermal energy by radiation
conduction convection radiation direct contact
The answer would be...... True it is.
radiation-energy transferred by waves or rays conduction-transfer of energy that occurs when molecules bump into each other (direct contact)
No! radiation is the transfer of energy in the form of electromagnetic waves.
We apply the term conduction to the transfer of thermal energy through direct contact. The other two mechanisms that transfer thermal energy are radiation and convection.
Some forces, such as gravity or the electrostatic force, can act without direct contact. If a force is applied over a certain distance (such as, when an object falls), work is done, i.e., energy is transferred. Ah, but what is direct contact? One electrostatic field pushing against another? If I touch something, it is the electrostatic fields pushing against each other. There is no direct contact!
