Convert radio frequency to temperature

AI Thread Summary
To convert radio frequency to temperature, Wien's law can be applied, specifically for blackbody radiation. The discussion highlights that the FM station frequency of 86.1 MHz can be analyzed using the formula fmax = (ak/h)(T). However, it is noted that the spectrum of FM broadcasts does not closely resemble blackbody radiation, suggesting that a direct conversion may not be meaningful. Participants express uncertainty about the applicability of the formula in this context. Ultimately, the conversion from radio frequency to temperature lacks practical relevance due to the differences in spectral characteristics.

Hello,

Is there a formula to convert a certain radio frequency to temperature? Thanks.

What exactly do you mean?
If you mean the temperature of a black that emits a frequency in the radio then use wein's law.

for example, the FM station abc operates at 86.1mhz, what's the temperature is the radio wave emitting?

i think i have found the formula though.

do i use the frequency form formula?

fmax = (ak/h)(T)
 
The spectrum of a FM broadcast is not very similar to the spectrum of blackbody radiation at any temperature. I don't think the conversion makes sense.
 

Thread 'Entropy and configurations of microstates'

I was watching a Khan Academy video on entropy called: Reconciling thermodynamic and state definitions of entropy. So in the video it says: Let's say I have a container. And in that container, I have gas particles and they're bouncing around like gas particles tend to do, creating some pressure on the container of a certain volume. And let's say I have n particles. Now, each of these particles could be in x different states. Now, if each of them can be in x different states, how many total...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
