Question

What is a phase in physics?

Answer 1

1. Phase is the position of a point in time on a cycle of a waveform.
2. Phase is a dimensionless quantity.
3. One complete cycle is ${360}^0$ is called the phase.
4. The phase is also expressed in terms of radians $1\text{radian}=57.3^0$
5. The phase also specifies the location.
6. The Phase angle refers to the angular component of a periodic wave.
7. A periodic wave represented by $A\angle \theta$
   Where A is the magnitude and $\theta$ is the phase angle.
8. Phase is the same frequency, same cycle, the same wavelength, but two or more waveforms not exactly aligned together.
