Question

13. Which of the following lines is not expected in absorption spectrum?
(1) 1—4
(2) 2-3
(3) 1-2
(4) 1-3​

Answer 1

Dear friend,

● Answer -

(2) 2-3

◆ Explaination -

• Absorption spectrum is observed when electron from ground state acquires energy and jump to higher energy levels.
• In 2nd option (2-3), electron is not jumping from ground state thus there will be no absorption spectrum.

# Extra information -

• Absorption spectrum is a spectrum of electromagnetic radiation transmitted through a substance, showing dark lines or bands due to absorption at specific wavelengths.

Thanks for asking..

Answer 2

Answer:

(2) 2-3

Explanation:

The transitions from the excited State to ground state will occur in the absorption spectrum so the spectral line (2-3) will not occur in the absorption spectrum because this is for the transition from higher excited state (3) to lower excited state (2) but not to ground state.

hope it helps you.
