Power Spectrum Density and Frequency if i have some random signals (sampling rate = 10Hz, 0.1s per data)

Using python library i transformed it to power spectral density

power spectral density forms = f, psd (using mlab.psd)

I'm really curious about f....

If f is 0.01, is it really means 0.01Hz or 0.1Hz(10Hz * 0.01Hz) in signal??

I confused about this conception

Is it relevant to sampling rate and psd frequency?

I'm really thank you for your help!
If you are asking about the grid resolution of the PSD then it is given by:

$$ \frac{{F}_{s}}{N} $$

Where $ {F}_{s} $ is the sampling rate and $ N $ is the number of samples.
Pay attention that you can increase the grid resolution by Padding the data with zeros.
Though it will increase the grid resolution it won't increase the resolution of the DFT (In the sense of resolution to see to close, in frequency, harmonic signals).
