Question
A pair of atoms naturally oscillate at a fixed frequency and amplitude at a constant temperature. As the atoms are cooled, this oscillation will eventually start to disappear. due to simple damping.
Which of the following statements best describe what is happening?
A transfer of thermal energy from the atoms to the environment is reducing the amplitude of the oscillations
A transfer of thermal energy from the atoms to the environment is reducing the frequency of the oscillations
A transfer of thermal energy from the environment to the atoms is reducing the amplitude of the oscillations
A transfer of thermal energy from the environment to the atoms is reducing the frequency of the oscillations
Explanation / Answer
When a damped oscillator is subject to a damping force which is linearly dependent upon the velocity, such as viscous damping, the oscillation will have exponential decay terms which depend upon adamping coefficient.
Option A) is correct.
A transfer of thermal energy from the atoms to the environment is reducing the amplitude of the oscillations
