Answer:
Explanation:
It is given that,
Initially, the electron is in n = 7 energy level. When it relaxes to a lower energy level, emitting light of 397 nm. We need to find the value of n for the level to which the electron relaxed. It can be calculate using the formula as :
R = Rydberg constant,
Solving above equation we get the value of final n is,
or
So, it will relax in the n = 2. Hence, this is the required solution.
