(III) Wavelength emitted by Atomic hydrogen in Interstellar space | (c) Short radio wave |
(IV) Wavelength of radiation arising from two close energy levels in hydrogen | (d) X-rays |
A) (I)-(A), (II)-(B), (III)-(B), (IV)-(C)
B) (I)-(A), (II)-(B), (III)-(C), (IV)-(C)
C) (I)-(D), (II)-(C), (III)-(A), (IV)-(B)
D) (I)-(B), (II)-(A), (III)-(D), (IV)-(A)
Correct Answer: D
Solution :
