Collision frequency unit conversion

Click For Summary
SUMMARY

The discussion clarifies that while collision frequency measured in collisions per second shares the same dimensionality as hertz (Hz), they are not identical units. Both hertz and becquerel (Bq) represent events per second but are used in different contexts; hertz refers to cycles, while becquerel pertains to radioactive decays. Understanding this distinction is crucial for accurate scientific communication.

PREREQUISITES
  • Understanding of frequency units such as Hertz (Hz) and Becquerel (Bq)

hi all

I have a question about unit for collision frequency. The unit is collision per second and is it same with hertz?

Thanks

Yes.
 
To elaborate: a "collision" is not a physical quantity, so it doesn't have a unit. Which leaves you with frequency (Hertz), which is actually a kind of artificial unit (derived), since it is any event per second.

They have the same dimensions but aren't necessarily the same unit. For example the becquerel .the unit of radioactive decays (1Bq is one decay per second), has the same dimensions as the hertz(1Hz is one cycle per second), but is not the same unit.

Yes, sorry, Bq and Hz are different units, same dimension (different name for the same concept).
