Question
- Why are infra-red waves often called heat waves? Explain.
- What do you understand by the statement, ‘‘Electromagnetic waves transport momentum’’?
✓
Answer
- Infrared waves are prdocued by vibration of atoms of molecules which increases the temperature due which they are also the cause of heat energy.
- Electromagnetic waves also show particle nature, i.e., they aslo behave as a matter according to Planks Quantum theory, So, they also possess some momentum and they can also change momentum.
