Question

How does the energy difference between the consecutive energy level vary as the quantum number $n$ increases?

• A. Increases
• B. Decreases
• C. Remains unchanged
• D. First increases and the decreases

Answer 1

Answer: (B)

Decreases

We know that, $E_n\propto \frac{1}{n^2}$.
As $n$ increases $(E_n-E_{n+1})$ decreases.
