The center frequency Fc = (fh + fL)/2 at that time RF system or filter is in resonance mode it gives max output by the filter system in terms of power, voltage and current. Centre frequency is critical in nature with output because power current in maximum finally afterwards at that freq. System RF or filter may go to damage or heating take place component may damage.

In band pass the filter will allow frequencies abouve fl and upto frequencies below fh so the center frequency will be thus from abouve formulae it is average of these two frequency.

Critical frequency is the maximum band pass frequency which allow to pass the bandwidth of the certain frequency.
It is equal to the fc=fh when bandwidth is equal to 1.
It is equal to the fc=fh when bandwidth is equal to 1.

Since aband pass filter is used to pass a particular band of frequency, the geometric average of critical frequency yields the center frequency.

The center frequency of a filter or channel is a measure of a central frequency between the upper and lower cutoff frequencies.

The critical frequency of a filter is defined as the point at which the response drops -3db from the passband.

fc = Critical frequency.
fh = High frequency.
fl = Low frequency.
fh = High frequency.
fl = Low frequency.

What does the critical frequency please said in detail?

Critical frequency is also called as cut off frequency.
