SATHEE: Atoms And Nuclei Question 52

Atoms And Nuclei Question 52

Question: The wavelength of the first line of Balmer series is $6563 A A$ . The Rydberg constant for hydrogen is about [MP PMT/PET 1998]

Options:

A) $1.09 \times 10^{7} p e r m$

B) $1.09 \times 10^{8} p e r m$

C) $1.09 \times 10^{9} p e r m$

D) $1.09 \times 10^{5} p e r m$

Show Answer

Answer:

Correct Answer: A

Solution:

$\frac{1}{λ} = R [\frac{1}{4} - \frac{1}{9}] = \frac{5 R}{36}$
$∴ R = \frac{36}{5 λ} = \frac{36}{5 \times 6563 \times 10^{- 10}} = 1.09 \times 10^{7} m^{- 1}$
