Correct answer: B
-
We match each electromagnetic wave with its standard wavelength range.
-
Recall the usual order of EM waves by decreasing wavelength:
- Now identify each range from List II:
-
III. to
This corresponds to Infra-red. -
II. to
This corresponds to Ultraviolet. -
IV. to
This corresponds to X-rays. -
I.
This corresponds to Gamma rays.
- Therefore the correct matching is:
- Compare with the options:
- Option B: ✅
Hence, the correct answer is Option B.
- Comparison with stored correct answer:
Stored correct answer is B, which matches the derived answer.
