In hydrogen atoms, transition from the state n=6 to n=1 result in ultraviolet radiation. Infrared radiation will be obtained in the transition

Options

  1. An =6 to n =2
  2. Bn =5 to n =3
  3. Cn =3 to n =5
  4. Dn =4 to n =2

Correct answer

C. n =3 to n =5

Step-by-step solution

1 = R ( 1 n ₁^2 - 1 n ₂^2 ) For UV ₁=1 and n ₂=6, 1 R 36 35 For infrared the wavelength must be greater the UV wavelength. For n ₁=3 and n ₂=5, 1 R 225 16 This is the largest wavelength we can get. So, it is the answer.
