Case 1: An electron jumps from energy level 3 to energy level 7 in an atom.
Case 2: An electron jumps from energy level 3 to energy level 9 in an atom.

For case 1, what happens when an electron jumps from energy level 3 to energy level 7 in an atom?

The light is getting absorbed for the given transition.

Explanation:

There are two ways in which electrons can transition between energy levels:

We are given:

Lower (Initial) energy level = 3

Higher (Final) energy level = 7

As, the electron is jumping from lower energy level to higher energy level. So, the light gets absorbed.

Hence, the light is getting absorbed for the given transition.
