Question

Use the Rydberg equation to calculate the frequency of a photon absorbed when the hydrogen atom undergoes a transition from n₁ = 2 to n₂ = 4. (R = 1.096776 × 10⁷ m^-1; c = 3.00 × 10⁸m/s) A) 2.06 × 10⁶ s^-1 B) 2.74 × 10⁶ s^-1 C) 6.17 × 10¹⁴ s^-1 D) 8.23 × 10¹⁴ s^-1 E) > 10¹⁵ s^-1

Quizplus · Accepted Answer

The Rydberg equation for frequency is given by ν = R * c * (1/n₁² - 1/n₂²). Substituting the given values, ν = 1.096776 × 10⁷ m⁻¹ * 3.00 × 10⁸ m/s * (1/2² - 1/4²) = 6.17 × 10¹⁴ s⁻¹.
