The wavelength of the first Balmer line caused by a transition from the n=3 level to the n=2 level in hydrogen is ₁ . the wavelength of the line caused by an electronic transition from n=5 to n=3 is :

Options

  1. A375 128 ₁
  2. B125 64 ₁
  3. C64 125 ₁
  4. D128 375 ₁

Correct answer

B. 125 64 ₁

Step-by-step solution

array l ₁ ₂ = 1 2² - 1 3² 1 3² - 1 5² = 1 4 - 1 9 1 9 - 1 25 = 125 64 ₂= 125 64 ₁ array
