A Brief Note on Periodic Wave Motion

In our knowledge, waves motions are crucial in determining the few significant aspects that constitute notions of frequency, amplitudes and as well as wavelength. All these determine what kind of motion is displayed by the respective waveforms. Moreover, these refer to three significant properties for measuring wave motions. Waves refer to disturbances that help in transferring one form of energy to another form with the help of a medium. In this study, an intensive exploration will be conducted that will help in clearing the concepts associated with periodic wave motions.

An Overview of Periodic Motions

In simple terms, period motion is repetitive motion that intends to reiterate itself within some equal intervals of time. For example, the tuning fork or pendulum seems to be one of the best examples for determining such motions. On effective analysis, it can be understood that these motions pass along the mean position after some specific interval of time. Both the waves are longitudinal as well as transverse wave motions. The significant notions such as frequency, amplitude and wavelength are used in determining the nature of waves, whether periodic or not. In addition to these, a characteristic velocity is to be noticed that is determined by the propagation of disturbances through the respective media.

What Are Wave Motions?

Waves refer to the disturbances that travel through medium and transport of the energies and if the term motion is associated with waves it refers to travelling of these disturbances. This further implies that from a state of equilibrium the disturbances seem to flow from one place to another in a regular and organised way. For example, related to the surface waves in seas and oceans. It needs to be noted that light, as well as sound waves, propagate as disturbances of waves. 

Properties of Periodic Wave Motions

Several objectives are noticed that are effectively displaced by period wave motions that are as follows.

• Amplitude refers to displacement of the wave at its maximum height from the resting position;
• Wavelength, distance that lies between two consecutive points on the wave;
• Period refers to the interval between two crates of wave;
• Speed, distance with a specific interval of time by propagating wave;
• Frequency is vibration that is occurring in every second  and 
• Phase respectively.  

Types of Periodic Wave Motions

Primarily two significant types of periodic wave motions are noticed that relate to transverse and longitudinal motion waves. Transverse waves cater to waves where particles within the medium seem to oscillate at right angles to the direction of advancement of the wave. Such as radio waves, electromagnetic waves and so on. On the other hand, longitudinal waves refer to waves where particles within the medium seem to exhibit a pattern of movement towards the direction associated with the propagation of the wave.

What Are Sinusoidal Periodic Motion?

These “Sinusoidal Periodic Motion” cater to motions that are periodic in nature. In this motion, the cycle gets repeated at equal intervals of time or radian of fixed amounts. These waves generally represent the natural phenomenon of changing states and how they are exhibited. The sine wave displays amplitude that is variable as it changes with time. For example, the variable may be an audible sound. Moreover, frequency of “Sinusoidal Periodic Motion” is denoted by the amount of cycles that get repeated per second.

Defining Simple Harmonic Motions

The term, “Simple Harmonic Motions” is quite frequent in its usage as it sets an example for periodic motion. In this, for a point, the periodic motion is exhibited through a straight line, in such a way that acceleration is associated with a notion that is always directed towards the fixed point within the line. Moreover, acceleration is proportional to the distance acknowledged from the point.

Conclusion 

In concluding the study, it is understood that the wave motions seem to exhibit several characteristics and one of the significant is that of displaying of periodic nature. Study also focuses on defining what wave motions with their relevant examples. Many notable characteristics are evidenced such as variations in pressure, movement of the particles within the medium as well as the changes that are acknowledged within the medium of propagations. Discussions are conducted on determining sinusoidal wave motions that refer to most natural representations. In addition to these, applications of simple harmonic motions are also explored.
