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 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
