The transition of an electron in hydrogen atom that emits a photon whose wavelength lies in the ultraviolet region of the electromagnetic spectrum is
  1. $5 \rightarrow 4$
  2. $4 \rightarrow 3$
  3. $3 \rightarrow 2$
  4. $2 \rightarrow 1$

Solution

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