Transcript of The difference between Mechanical and Electromagnetic Waves

Mechanical & Electromagnetic Waves By Sarah Doyle Mechanical waves are... A mechanical wave is a disturbance that moves through a medium. The medium itself doesn't go anywhere... BUT Elctromagnetic waves are.., Electromagnetic waves are transverse waves consisting of changing eletric fields and changing magnetic fields Mechanical waves are produced when some kind of energy moves a substance, a material, or a "thing" within a medium that will conduct the mechanical energy of motion away from the source! AND Mechanical waves require matter to travel... the material through which the mechanical waves travel is called a MEDIUM! SOLIDS... LIQUIDS... GASES... Elecromagnetic waves are produced
by consistently changing fields. Electromagnetic waves travel through a vacuum, or empty space as well as matter. Waves & particles are two different types of Electromagnetic waves. The three main types of Mechanical waves are transverse, longitudinal, and surface waves! properties of mechanical waves are frequency, period, wavelength, wave speed, crest, trough and amplitude. Properties of electromagnetic waves are wavelength & frequency. electromagnetic waves can carry energy
but cannot transport matter!!! mechanical waves..... Reflect... Refract... AND Diffraction... DIFFERENCES
