Question:
Identify the INCORRECT statement about the black body radiation
Identify the INCORRECT statement about the black body radiation
Show Hint
Recall the shape of the black body spectrum with its peak wavelength.
Updated On: Nov 12, 2026
- Intensity is same for all wavelengths.
- Intensity is maximum for a particular wavelength.
- Intensity is less for longer wavelengths.
- A black body emits all wavelengths.
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept
A black body emits radiation of all wavelengths, but the intensity is not uniform.
Step 2: Spectrum
The intensity rises to a maximum at one wavelength and falls for longer and shorter wavelengths.
Step 3: Conclusion
The statement that intensity is the same for all wavelengths is incorrect.
Final Answer:
The statement that intensity is the same for all wavelengths is incorrect. \[ \boxed{\text{(A) }\text{Intensity is same for all wavelengths.}} \]
