Question

According to the Bohr Theory, which of the following transitions in the hydrogen atom will give rise to the least energetic photon?

• A. n = 5 to n = 3
• B. n = 6 to n = 1
• C. n = 5 to n = 4
• D. n = 6 to n = 5

Answer 1

Answer: (D)

n = 6 to n = 5

Answer 2

$E = \frac{hC}{\lambda} = hC \, R_H \left[ \frac{1}{n_1^2} - \frac{1}{n_2^2}\right]$
