Amplitude and Phase

Wave motion happens when a periodic disturbance of some kind is propagated through a medium except Electromagnetic waves.  Each medium has a specific velocity at which the disturbance moves.

There are three techniques to measure wave motion: amplitude, wavelength, and frequency. Pressure variations in the air, transverse motions along a guitar string, and variations in the intensities of local electric and magnetic fields in space, which make up electromagnetic radiation, are all examples of wave motion.

Phase

Phase is  the relationship between two or more signals of the same frequency. The phase refers to the relationship between the positions of two waveforms amplitude crests and troughs.

Distance, time, and degrees can all be used to calculate phase. The peaks of two signals with the same frequency are said to be in phase if they are exactly aligned at the same time. In contrast, two signals of the same frequency are said to be out of phase if their peaks are not exactly aligned at the same time.

Rather than being expressed as a fraction of a wave cycle, a phase difference is usually written as an angle. Because the waveform of a pure tone with a single frequency can be represented using the trigonometric sine function, the phase difference can be expressed as an angle.

y(t)=A Sin(2π ft)

Y (t) = is the waveform

A is the amplitude

f is frequency 

t is time.

Amplitude

The maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position is called amplitude in physics. It is equal to one-half of the vibration path’s length. The amplitude of a pendulum is thus equal to one-half of the distance traversed by the bob as it moves from one side to the other. Waves are produced by vibrating sources, and their amplitude is proportional to the source’s amplitude.

The maximum displacement of any point on the string from its location when the string is at rest is used to calculate the amplitude of a transverse wave, such as the wave on a plucked string. The maximum displacement of a particle from its equilibrium location is used to calculate the amplitude of a longitudinal wave, such as a sound wave. The amplitude of a wave is said to be damped when it steadily falls as its energy is lost.

Wave displacement

In two dimensions, the only feasible orientations for displacement are parallel to or perpendicular to the wave’s travel path. To make things easier, we’ll name the wave’s flowing direction horizontal and the perpendicular direction vertical. The x and y axes can then be used to visually display these.

There is simply vertical displacement in the wave on our jump rope. The particles of the jump rope are being displaced, and the rope is simply moving vertically up and down. Keep in mind that the rope is not moving horizontally with the wave.Conclusion

In this article we have studied Phase and amplitude.The waveforms of all sine waves mix at each position along the waveform to make a sound when more than one sine wave is combined to create a sound.
