Explanation of Terminologies in Progressive Wave Motion

Progressive waves and their different terminologies are the main points of attraction in this field. Progressive wave motion has different characteristics and there are also many ways in identifying progressive waves. Wave height, a crest of a wave, wavelength and wave trough are the terms used in a wave motion. Progressive waves can be described through frequency, speed, amplitude and path difference. Another part of the discussion in this field is wavelength and wave velocity. 

Analysis on Wavelength 

It is the distance between the corresponding two consecutive waves. Here corresponding points refer to those points or it is the particle of the same phase. It is an important parameter of the waves and is the distance between two points on the wave. Some important parameters of wavelength are:

• Frequency
• Speed of the wave

Sound travelling in the air, ripples in the water and coordinated vibrations of the objects are examples of the waves. These can be observed in daily life and are a good way to visualise waves. 

Discussion on a Progressive Wave

Progressive waves are considered to be waves that travel in a medium. It travels continuously within the medium in the same direction without any change in its amplitude. This is called the progressive wave of the travelling wave. Different characteristics of this particular wave can be seen. All the vibrating particles of the medium have the same amplitude and the same frequency. The particles change from one particle to another and one remains permanently at rest. It can be identified by observing its continuity in travelling without any change. Longitudinal waves and transverse waves are the two main types of this wave. Ocean waves, seismic waves and sound waves are examples of these types of waves.   

What Terms Are Used in Wave Motion?

Wave motion consists of the terms like wavelength, wave trough, wave crest and height of a wave. The wave crest among them seems to be the highest part of a wave. On the other hand, the lowest part is the wave trough. Wavelength describes the distance between two consecutive wave crests. It can be between two consecutive wave troughs. Wavelength here describes the vertical distance between the wave crest and wave trough.     

Characteristics of Progressive Wave Motion

Progressive wave motion travels continuously in a medium and in the same direction. The characteristics say all vibrating particles of ten mediums have the same amplitude. It also contains the same frequency but the same phase changes from one particle to another. The particles are changed from one to other particles and no one remains permanently in rest. The four characteristics of wave motion are wavelength, speed, amplitude and frequency. The main characteristic says that it travels continuously without any change or stop.     

What Is Wave Velocity?

It is the distance, traversed by a cyclic or periodic, motion per unit of time. In common language wave velocities are speed and direction. Wave velocity is equal to the product of its frequency and wavelength. It can be seen as independent in nature of its intensity. A wave has travelled a distance per unit of time and it is the wave velocity and it can also be called the speed. The velocity of a wave depends upon the medium’s nature. This velocity is also famous as the phase velocity. Mathematically it can be said as:

v=w/k

Here, ‘v’ stands for wave velocity, ‘k’ is the angular wave number and ‘w’ means the angular velocity.       

A Short Note on Three Types of a Progressive Wave

Three types of progressive waves are the Orbital waves, transverse and longitudinal waves. Longitudinal here are the particles that move back and forth in the direction of the energy transmission. Energy can be seen as transmitted through all states of matter. In orbital waves, particles are moved in a circular way. Energy is transmitted by these waves along with interference between two fluids of different densities. A transverse wave defines the moving of particles back and forth at right angles towards the direction of energy transmission. These particles here transmit energy through solids.  

Conclusion

The discussion is going on about progressive motion and it is an important part of physics. Progressive wave motion and its different terminologies are described throughout the whole study. Here three types of progressive waves can be seen and wave velocity is an important aspect here. Characteristics of the progressive wave motion and analysis of wavelength are important in this study. Wave velocity here refers to speed and direction. It is equal to the frequency and wavelength of the product.
