When a source of energy causes a medium to vibrate, a mechanical wave is formed. Mechanical waves require a medium to travel. There are two different types of mechanical waves: longitudinal and transverse waves. The major difference between them is that the transverse waves the displacement of the medium to the direction of propagation of the wave is perpendicular and in the longitudinal is parallel.
The wave travels in the same direction as the medium vibrates. Longitudinal waves are sound waves in air. The …show more content…
When a transverse wave is a high point is called a crest, and when it's on a low point is called trough. An example of a transverse wave could be a ripple on a pond. Concentric circular ripples which move outward from the point of impact will produce when a pebble is thrown into a pond. A tossed pebble provides the energy to generate a traveling wave. http://hyperphysics.phy-astr.gsu.edu/hbase/Sound/tralon.html Electromagnetic waves “A transverse wave that involves the transfer of electric and magnetic energy (Don Buckley, 2011)” they are made of vibrating magnetic and electric fields that move through a medium or space at the speed of light.
B. SOUND “Sound is a disturbance that travels through a medium as a longitudinal wave ( Don Buckley, 2011 )”. Normally when energy is transferred from one place to another a disturbance is involved. Sound waves can transport the energy through a medium air, water, and solid materials. Temperature, stiffness, and density can affect the speed of
