Question

The difference between I and II energy levels is

• A. $1.5\times {10}^{-18}J$
• B. $3\times {10}^{-18}J$
• C. $6\times {10}^{-18}J$
• D. $12\times {10}^{-18}J$

Answer 1

The correct option is A $1.5\times {10}^{-18}J$

For this particle in the box: $E=\frac{n^2{h}^2}{8m{L}^2}$

The difference between I and II energy levels is:
$E_{diff}=\frac{3h^2}{8m{L}^2}=1.5\times {10}^{-18}J$
