![]() ![]() Mechanical waves transfer energy from one point to another via particle movement within the medium itself, while electromagnetic radiation transfers energy through electric and magnetic fields which oscillate at right angles to each other as well as in the direction of wave propagation. ![]() Mechanical waves require a medium for transmission such as air or water, whereas electromagnetic waves do not need a medium for transmission – they can travel through vacuum! This is why we can see stars millions of light years away despite there being no physical connection between us and them. Examples of transverse waves include light, water ripples, and seismic S-waves examples of longitudinal waves include sound and seismic P-waves. Transverse waves are characterized by particles that move perpendicular to the direction of wave travel, while longitudinal waves have particles that move parallel to the direction of wave travel. Waves come in two main types: transverse and longitudinal. These ripples spread outwards from their point of origin as the energy from the disturbance moves through the water – this phenomenon has been observed since ancient times with Aristotle noting how circular ripples form when stones were thrown into still pools. Light on the other hand is an electromagnetic wave that does not require a medium for propagation it travels at about 300 million meters per second in vacuum! Water waves are also mechanical waves caused by disturbances on the surface of water bodies like oceans or ponds. Sound is an example of a mechanical wave that requires a medium to travel through it is created by vibrating objects which cause air molecules to vibrate back and forth creating pressure variations that propagate outward from the source. Waves come in many forms, such as sound waves, light waves, and water waves. Waves are a fundamental concept in physics, and can be defined as the transfer of energy through a medium without any net movement of matter. ![]()
