Mechanical waves:
Mechanical waves are the waves which need a medium to travel and transfer their energy while on the other hand non-mechanical wave’s does not require a material medium to travel. Longitudinal and transverse are two types of wave motion of the mechanical waves which have the capability to travel through a medium which could be gas, liquid or solid at the wave speed which totally depends on the properties of that medium. Waves in the water of sea could be the example of the mechanical waves.
Scalar Waves:
Scalar waves are also known as longitudinal and Tesla wave’s .They has much importance in the practical and technological field related energy sciences.
Path of Oscillation:
It oscillates in the direction which is same to their

Wave production due the movement of our hand up and down is called linear polarized wave while if we move our hand in the circular form and generate transverse waves then it’s called circular polarized wave.
As this wave can be generated by moving hand in two types of motions that is why it exhibits two-dimensional motion
Electromagnetic waves;
These waves bear momentum and do not require a material medium for their propagation, waves travel though magnetic and electric fields and have light velocities while their movement in the vacuum. For example radio and light waves. These waves can be polarized as well and in nature they could be transverse
S-Waves:
S-waves are similar to the transverse waves and are the type of the waves which travel though the objects body, as compared to the surface waves that travels on the surface of the body. Divergence does not occur in the s-waves. In s-waves, meaning of s is secondary wave and they are named secondary because they are the second one to arrive during the earthquake, polarization is one of the properties of

Interference could be of two types
Constructive Interference:
If two waves with same wavelength superpose and crust of one wave meets the crust of the other wave then they reinforce each other and interference occurs and in this case a wave with double amplitude but same frequency is formed.
Destructive Interference:
If two waves with same wavelength overlap and crust of one wave meets with the trough of the other wave, in this way they cancel each other effect and destructive interference occurs and as a result they make one wave
Constructive Interference Destructive interference
Diffraction:
Diffraction is the phenomena in which wave comes in contact with an obstacle. It occurs in sound waves, electromagnetic waves, water waves and visible light waves.
Basically it’s the bending of the wave when it passes through the narrow slit or the obstacle point and in this way dark and light fringes are formed. It is to be noted that if wavelength is large then the diffraction caused will be large. Gap larger than the wavelength will cause less spreading and a gap similar to the wavelength will cause large spreading as shown in figure 1 and

Earthquakes play a major role into understanding the composition and materials that exist within the Earth (Merali and Skinner, 2009, p.252). Earthquakes are the main source of insight into the inner workings of the earth, due to the nature of the seismic waves they produce. P and S waves are reflected and refracted at different boundaries within the earth, and this enables seismologists to make inferences about the internal composition and structural of planet Earth. (Merali and Skinner, 2009, p.252).

Rough waves are an open water phenomenon, in which winds, currents, nonlinear phenomena cause a wave to briefly form that is far larger than the "average" large occurring wave of that time and place. rogue waves can form in large bodies of freshwater as well as the ocean. The first rogue wave confirmed with scientific evidence,it has a maximum height of 25.6 metres (84 ft).rogue waves can also reach up to about 30 meters or 100 feet high. A rogue wave estimated at 18.3 meters (60 feet) in the Gulf Stream off of Charleston, S.C.
Ultrasound is sound waves that have a frequency above human audible. (Ultrasound Physics and Instrument 111). With a shorter wavelength than audible sound, these waves can be directed into a narrow beam that is used in imaging soft tissues. As with audible sound waves, ultrasound waves must have a medium in which to travel and are subject to interference. In addition, much like light rays, they can be reflected, refracted, and focused.
As said above, both light and sound waves have to do with interference. In sound, interference affects both the loudness and amplitude. When two waves’ crests overlap, the amplitude increases. The same is true with the troughs of the waves, which decrease the amplitude.
Refraction occurs when light travels from one medium crosses a boundary and enters another medium of different properties. For example, light traveling from air to water. The amount of refraction (or bending) can be calculated using Snell's Law.

Sound is essentially a wave produced by a vibrating source. This compression and rarefaction of matter will transfer to the surrounding particles, for instance air molecules. Rhythmic variations in air pressure are therefore created which are detected by the ear and perceived as sound. The frequency of a sound wave is the number of these oscillations that passes through a given point each second. It is the compression of the medium particles that actually constitute a sound wave, and which classifies it as longitudinal. As opposed to transverse waves (eg. light waves), in which case the particles move perpendicular to the direction of the wave movement, the medium particles are moving in the same or opposite direction as the wave (Russell, D. A., 1998).
In 1801 Thomas Young provided some very strong evidence to support the wave nature of light, he placed a monochromatic light in front of a screen with two slits cut into it, and observed an interference pattern, only possible if light was a wave. In 1965 Richard Feynman came up with a thought-experiment that was similar to Young’s experiment. In Feynman’s double-slit experiment, a chosen material is fired at a wall which has two small slits that can be opened and closed at will – some of the material gets blocked and some passes through the slits, depending on which ones are open.
