How is radiation different from conduction and convection?
Understand the Problem
The image contains educational content regarding visible light and the electromagnetic spectrum, discussing concepts related to heat transfer, properties of electromagnetic waves, and the historical perspective of Isaac Newton's contributions to the understanding of light.
Answer
Radiation transfers heat via electromagnetic waves, not requiring a medium.
Radiation is different from conduction and convection because it transfers heat through electromagnetic waves, without requiring a medium, unlike conduction and convection which need matter as a medium for heat transfer.
Answer for screen readers
Radiation is different from conduction and convection because it transfers heat through electromagnetic waves, without requiring a medium, unlike conduction and convection which need matter as a medium for heat transfer.
More Information
Radiation can occur in a vacuum, such as space, unlike conduction and convection which require matter.
Tips
A common mistake is assuming all heat transfer needs a medium; remember, radiation does not.
