Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Thermal radiation is emitted by all bodies due to their temperature and lies mainly in the infrared region.
Step 1: Nature of thermal radiation.
Hot objects emit radiation predominantly in infrared wavelengths.
Step 2: Conclusion.
\[ \therefore \text{Thermal radiation lies in infrared region} \]
