Question

An electron during its transition from second excited state to ground state,emits radiation of wavelength λ. Answer the following a. In which series of transition this emission lines? Justify your answer. b.Name the region of electromagnetic wave spectrum.​

Answer 1

Given:

An electron during its transition from second excited state to ground state,emits radiation of wavelength λ.

To find:

• Series of transition ?
• Region of Emission Spectrum?

Solution:

• The series of transition is BALMER TRANSITION.

• In this kind of transition, the electron from 2nd shell excited state to the ground state. The decrease in energy of the electron is manifested as formation of Electromagnetic Waves.

_________________________

• The electromagnetic waves produced due to this transition fall under VISIBLE SPECTRUM.

• The wavelength ranges from 400 nm to 720 nm.
