The Simple Harmonic Oscillator (SHO) in one dimension is a fundamental concept in physics and quantum mechanics. It describes the motion of a particle that is subjected to a restoring force proportional to its displacement from a fixed equilibrium position. In a one-dimensional SHO, the particle can move only along a straight line.
Explanation:
According to uncertainty principle
For SHO <x> = 0
→ Calculating value of <x>2
V = 1/2 kx2
According to Viral Theorem of SHO,
Where,
<T> = Average Kinetic energy
<V> = Average Potential energy
Therefore,
or,
According to Vibrational quantum,
Where, n = no. of nodes
...
or, En = 7Eo
Putting the value of En in eq(2)
...
Now, putting the value of<x2> in eq (1)
Conclusion:
Therefore, the uncertainty of the particle in 1-D SHO is
