What is a phase shift, and how does it relate to the frequency of the wave?

[Author ORCID: 0000-0003-1871-7803]

A phase shift refers to the displacement of a wave form in time. A complete wave cycle, also known as a period (T), corresponds to a phase shift of 360 degrees or 2π radians.

When representing a complete wave cycle in degrees (°), it can be denoted as T(deg). In this notation, T(deg) represents the angular measure of one complete cycle of the waveform in degrees.

In terms of frequency (f), which represents the number of wave cycles per unit of time, there is an inverse relationship between the period and the frequency. The period (T) is the reciprocal of the frequency (f), and the relationship can be expressed as: 

• T = 1 /f

If we express the period in degrees, T(deg), the relationship still holds

• T(deg) = 360° / f

In this case, T(deg) represents the angular measure of one complete cycle of the waveform in degrees, and it is inversely proportional to the frequency (f). Phase shifts can occur under the effects of relative velocities of observers and gravitational potential differences. 

These effects can introduce changes in the perception of time and the behavior of clocks, which may manifest as phase shifts in oscillatory systems and cause errors in time between relative clock oscillations under the effects of both relative velocities an. gravitational potential differences.
