The cutoff frequency is the minimum frequency that is required for the emission of electrons from a metallic surface, due to incident radiation . Below the cutoff frequency, the phenomenon of the photoelectric effect stops altogether.

This geometric mean value is calculated as being ƒr 2 = ƒ (UPPER) x ƒ (LOWER). A band pass filter is regarded as a second-order (two-pole) type filter because it has “two” reactive components within its circuit structure, then the phase angle will be twice that of the previously seen first-order filters, ie, 180o.
Read moreWhat is the formula for corner frequency?
This “Cut-off”, “Corner” or “Breakpoint” frequency is defined as being the frequency point where the capacitive reactance and resistance are equal, R = Xc = 4k7Ω . When this occurs the output signal is attenuated to 70.7% of the input signal value or -3dB (20 log (Vout/Vin)) of the input.
Read moreWhat is corner frequency in control system?
In physics and electrical engineering, a cutoff frequency, corner frequency, or break frequency is a boundary in a system’s frequency response at which energy flowing through the system begins to be reduced (attenuated or reflected) rather than passing through .

Read moreWhat is a waveguide beyond cutoff?
Editorial Team – everything RF The cut-off frequency of a waveguide is the frequency above which signals will propagate through it with minimal attenuation . This means that signals with a frequency above the cut-off frequency will propagate through a waveguide and signals below this frequency will be attenuated.4 Kas 2019
