Paper: CSIR NET June 2013 · Subject: Physical Chemistry · Chapter: Quantum Chemistry · Topic: Quantum Chemistry – General · Marks: 2 · Difficulty: Medium
The wave function $\psi$ of a certain system is the linear combination $\psi = \sqrt{\frac{1}{4}}\psi_1 + \sqrt{\frac{3}{4}}\psi_2$ where $\psi_1$ and $\psi_2$ are energy eigen functions with eigen values (non-degenerate) $E_1$ and $E_2$ respectively. What is the probability that the system energy will be observed to be $E_1$ ?
(a)$\sqrt{\frac{3}{16}}$
(b)$\frac{3}{4}$
(c)$\frac{1}{4}$
(d)$\sqrt{\frac{1}{4}}$
