Question

1st emission line of balmer seires is from paschen series?

Answer 1

False

Answer 2

The question asks whether the 1st emission line of the Balmer series originates from the Paschen series.

1. Balmer Series: This series corresponds to electron transitions where the electron falls to the n=2 energy level.

   • The 1st emission line (H-alpha) in the Balmer series corresponds to the smallest energy transition, which is from n=3 to n=2.

2. Paschen Series: This series corresponds to electron transitions where the electron falls to the n=3 energy level.

   • Lines in the Paschen series originate from higher energy levels (n=4, 5, 6, ...) and end at n=3.

Comparing the two:

The 1st emission line of the Balmer series is a transition from n=3 to n=2. This transition ends at n=2, not n=3. Therefore, it is not a line belonging to or originating from the Paschen series. The statement is false.

Explanation:

The 1st emission line of the Balmer series is the H-alpha line, which results from an electron transition from the n=3 energy level to the n=2 energy level. The Paschen series consists of spectral lines produced when an electron transitions from higher energy levels (n > 3) to the n=3 energy level. Since the Balmer series transition (n=3 to n=2) ends at n=2, it is not part of or originating from the Paschen series.
