In principal, you get $\text{Ws}=\text{J}$ for energy and $\text{W}$ for power, but as you are calculating these measures from a wav-file, you do not get any unit. What you get is just a ratio to the maximum possible value of a wav-file. A square wave with amplitude one has a level (power) of $0\text{ dBFs}$, which means dB Fullscale. Your signal has roughly ...

You don't need to know the phase at all and you only need to know the frequency approximately. It is the job of your digital carrier recovery scheme to estimate and remove the phase and residual frequency offset.

Its IES or Gate question having last option which you didn't mention here as "carrier frequency can not disappear." . Here correct answer among these 4 option is b i.e. the amplitude of any sideband depends on modulation index . . 2.Frequency spectrum of FM is analysed using Bessel's function .FM spectrum theoretically has infinite number of sidebands . Each ...

You have to pass sr=fs as well as hop_length=hop_length to the specshow function, as its default values are different from yours.

The best way to accomplish your desired result is to estimate the parameters of the interfering tone(s) and remove it(them) from the signal in the time domain. To get you started on how to go about this, I recommend you read these two articles of mine: Two Bin Exact Frequency Formulas for a Pure Real Tone in a DFT Phase and Amplitude Calculation for a Pure ...
