Question

A vibrating mass spring system has a frequency of 0.56 hz. how much energy of this vibration is carried away in a one-quantum change?

Answer 1

The energy carried away in a one-quantum change is given by

`E=hf`
where
h is the Planck constant
f is the frequency of vibration

For the system in this problem, the frequency of vibration is
`f=0.56 Hz`, therefore the energy of one quantum of vibration is

`E=hf=(6.6 \cdot 10^(-34) Js)(0.56 Hz)=3.7 \cdot 10^(-34) J`
