Match the List-I (Phenomenon associated with electromagnetic radiation) with List-II (Part of electromagnetic spectrum) and select the correct code from the choices given below this lists:
(I)-(A), (II)-(B), (III)-(B),,(IV)-(C)
(I)-(A), (II)-(B), (III)-(C), (IV)-(C)
(I)-(D), (II)-(C), (III)-(A), (IV)-(B)
(I)-(B), (II)-(A), (III)-(D), (IV)-(A)
Solution
Let's match the phenomena associated with electromagnetic radiation with the part of the electromagnetic spectrum.
1. **Wavelength emitted by atomic hydrogen in interstellar space** - This occurs in the radio wave region of the electromagnetic spectrum. Hence, I matches with D.
2. **Doublet of sodium** - The sodium doublet is a pair of yellow lines in the visible spectrum of sodium, hence, II matches with B.
3. **X-ray diffraction** - As the name implies, this phenomenon is associated with X-rays. Hence, III matches with C.
4. **Photoelectric effect** - The photoelectric effect is usually observed in the ultraviolet region of the electromagnetic spectrum. Hence, IV matches with A.
So, the correct matching would be I-D, II-B, III-C, IV-A.
Checking the options, we find that this matching corresponds to Option C.
Hence, the correct answer is Option C.
