The transition of an electron in hydrogen atom that emits a photon whose wavelength lies in the ultraviolet region of the electromagnetic spectrum is

  • A
    $5 \rightarrow 4$
  • B
    $4 \rightarrow 3$
  • C
    $3 \rightarrow 2$
  • Correct answer
    D
    $2 \rightarrow 1$

Solution

Ultraviolet region i.e., Lyman series so photon whose wavelength lies in the ultraviolet region of the electromagnetic spectrum is $2 \rightarrow 1$.

Hence, the correct answer is option: 'D'.
