Inductive reactance is proportional to frequency... XL = 2 pi f L ... so, the higher the frequency, the higher the reactance. At a sufficiently high frequency, the inductor would appear to be an open circuit. Note, however, that at very high frequencies, parasitic capacitance becomes a factor.
finding h parameters involves open and short circuits which is difficult to obtain at high frequencies due to stray inductance and capacitance
The skin effect in high-frequency electrical circuits causes the flow of current to be concentrated near the surface of the conductor, leading to increased resistance and power loss. This can affect the efficiency and performance of the circuit by reducing signal quality and increasing heat generation.

If the length of a wire increases, the frequency of the signal it can carry decreases. This is because longer wires have more capacitance and inductance, which create a low-pass filter effect that attenuates higher frequencies. As a result, longer wires are less efficient at transmitting high-frequency signals.

A High Pass Filter is an Electronic Filter that passes high frequency signals but Attenuates (reduces the Amplitude ) of Signals with frequencies lower than the cut-off Frequency

As the frequency becomes higher then its wavelength would decrease. In case of mechanical waves such as sound waves higher frequency means higher the pitch. In Sanskrit it is known as 'shruthi'. Singers would sing at different shruthi. In case of electromagnetic wave such as light, as frequency increases the colour changes. So highest frequency in the visible region will be the violet and the lowest is the red. Also the energy of the wave photon is given by the expression E = h nu, where nu is the frequency of the wave. So higher the frequency higher the content of energy in the photon compared to the lower frequency radiation.
The output frequency corresponding to logic 1 in digital data is typically referred to as the "high frequency" or "logic high frequency." In digital circuits, this frequency represents the signal level that indicates a binary 1. The specific frequency can vary depending on the design and application of the digital system.
A: Is the same as low frequency except it becomes a predominant factor.
