Atomic Structure Question 49

Question: The wavelength of the radiation emitted, when in a hydrogen atom electron falls from infinity to stationary state 1, would be (Rydberg constant =,1.097,×,107m1 ) [AIEEE 2004]

Options:

A) 406 nm

B) 192 nm

C) 91 nm

D) 9.1,×,108nm

Show Answer

Answer:

Correct Answer: C

Solution:

1λ=R,[1n121n22]

1λ=1.097×107m1[11212]

λ=91×109m We know 109=1,nm So λ=91nm
