Question

The Balmer series for the H-atom can be observed

• A. if we measure the frequencies of light emitted when an excited atom falls to the ground state.
• B. if we measure the frequencies of light emitted due to transitions between excited states and the first excited state.
• C. in any transition in a H - atom
• D. as a sequence of frequencies with the higher frequencies getting closely packed.

Answer 1

Answer: (B), (D)

if we measure the frequencies of light emitted due to transitions between excited states and the first excited state.
as a sequence of frequencies with the higher frequencies getting closely packed.

When electron jumps from higher energy level to first energy level, the spectrum of light is called Balmer series . Spectrum lines becomes closer if electron jumps from higher energy level to ground level . Hence, verifies answers (b) and (d).
