How Does Quantized Energy Affect Oscillation Amplitude?

AI Thread Summary
The discussion centers on the relationship between quantized energy and oscillation amplitude in a spring-mass system, specifically an atom in a crystal lattice. The energy of oscillation is calculated using E=nhv, resulting in 6.626E-21 J for one energy quantum. It is noted that energy is proportional to the square of the amplitude (A^2), prompting questions about the explicit relationship for a spring. Additionally, the impact of the atom's mass on amplitude is raised, indicating that mass plays a role in determining oscillation characteristics. Understanding these relationships is crucial for analyzing oscillatory systems at the quantum level.

Energy and Amplitude of Oscillation

An atom in a crystal lattice can be regarded as having a mass of 2.0E-26 kg attched to a spring. The frequency of this oscillator is 1.0E13 Hz. What is the amplitude of oscillation if the energy of oscillation is one energy quantum?

I know E=nhv, here n=1
so the energy of oscillation=> E=1h(1.0E13 Hz)= 6.626E-21 J

How does this relate to amplitude? (Energy is proportional to A^2?)
How does the mass of the atom affect this?

Hi Quelsita,

If it is modeled as a spring, then yes, the total energy is proportional to the square of the amplitude. But what is the explicit relationship for a spring?

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
