When an electron jumps from n = 5 to n = 2 having wave number equal to 2.3 x 16 m-1. In which spectral series will it fall?
- A
Lyman
- B
Balmer
- C
Visible
- D
Infrared
Correct option is B.
The Balmer series is the name given to a series of spectral emission lines of the hydrogen atom that result from electron transitions from higher levels down to the energy level with principal quantum number 2.
This option is incorrect because in lyman series an electron makes a transition from any outer orbit to first orbit i.e. \[n = 1\].
This option is correct because the Balmer series is the name given to a series of spectral emission lines of the hydrogen atom that result from electron transitions from higher levels down to the energy level with principal quantum number 2.
This option is incorrect because the visible light spectrum is the segment of the electromagnetic spectrum that a human eye can view. More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers.
This option is incorrect because Infrared is electromagnetic radiation with wavelengths longer than those of visible light and shorter than radio waves. It is therefore invisible to the human eye.
