AI Thread Summary
Rev/s can indeed be converted to Hz, as both represent frequency measurements, with 1 rev/s equating to 2π rad/s in angular frequency. The distinction lies in the context: rev/s is often used for rotational motion, while Hz is a general unit for cycles per second. Frequency is fundamentally defined as s^-1, making it interchangeable in terms of units. In practical applications, Hz is commonly used in various technologies, such as computer clocks and microwave ovens, which measure oscillations per second. Understanding this relationship clarifies how different frequency units can be applied across various scientific contexts.

for the frequency of revolution of electrons, the unit is expressed as rev/s
but for the frequency of a photon, the unit is hz


my question:
can rev/s also equal hz?
 
Physics news on Phys.org
Well frequency is really just s^-1

Saying the "frequency of revolution" however qualifies the "rev/s" because you have frequency... "/s"... and revolutions "rev".

Yes it can. 1 rev/sec is equal to 2pi rad/sec. This is angular frequency. If you look in elementary texts on circular motion, there's a directly relationship between angular frequency and the "usual" frequency.

Zz.
 
so if i see frequency, i can just use hertz, right?
 
You will also see cycles/sec a lot of times for units of frequency.
 
Hz is any COUNT per second ... your computer uses Mega "pulses per second", because its clock oscillates with a lot of "oscillations per second" , and the microwave oven produces even more "waves per second".
 
thank you very much!
