Waves are vibrations (sometimes called _____________) moving from one place to another. Waves travel through a __________, a material through which a wave transfers energy. This medium may be a solid, liquid or a gas. energy oscillations medium Types of Waves : Types of Waves Transverse Waves Longitudinal Waves Transverse waves and longitudinal waves are considered ________________ because they have to travel through a medium. mechanical Transverse Waves : Transverse Waves With this type of wave, the particles of the medium vibrate at right angles to the direction that the energy travels. This is where the name transverse comes from - it means ____________. across Longitudinal Waves : Longitudinal Waves The energy of the wave travels along in the same direction as the particles vibrate. Sound waves are ___________________ waves. compressional Compressional wave rarefaction compression Anatomy of a Wave : Anatomy of a Wave Wave – Crests & Troughs : Wave – Crests & Troughs Wave – Amplitude : Wave – Amplitude The distance from either a crest to the medium or the trough to the medium. Wave – Wavelength : Wave – Wavelength The distance from a crest to a crest or a trough to a trough. Or, two midpoints of a wave. Anatomy of A Wave : Anatomy of A Wave ? - stands for wavelength amplitude Waves in Action : Waves in Action The frequency of a wave refers to how many wavelengths pass a given point during a certain time. Frequency is measure in hertz. Key Terms frequency Waves in Action : Waves in Action Key Terms period The period of a wave refers to time it takes one wave to pass a given point Waves in Action : Waves in Action Key Terms refraction Refraction is the bending of a wave caused be a changed in speed as it moves from one medium to another. Waves in Action : Waves in Action reflection Law of Reflection angle of incidence is equal to the angle of reflection. Slide 16: The Magic Trianglevelocity v t d The Magic Triangle : The Magic Triangle v = f? v f ? Velocity of a wave f – stands for frequency Anatomy of a Wave : Anatomy of a Wave A B D C E wavelength amplitude Half a wavelength Double amplitude Half a wavelength You do not have the permission to view this presentation.
