Properties of Waves (Part 2) Textbook Chp 13, pg 255-272

Recall When direction of wave and direction of vibration is perpendicular to each other, the wave is called a transverse wave There are two types of waves: Transverse Waves Longitudinal Waves A longitudinal wave is when the wave direction and vibration direction are parallel to each other

Slinky Demo

Longitudinal Wave Look at the animated gif below Observe the direction of the wave Observe the movement of the red particle

Longitudinal Wave The wave moves from left to right The particle vibrates left and right The direction of the wave is parallel to the direction of vibration of the particles Important note: even though the direction is parallel, the particles DO NOT travel along with the wave. They are still vibrating around fixed position.

Parts of Longitudinal Waves A transverse wave has crests and troughs A longitudinal wave has compressions and rarefactions A wavelength is measured from compression to compression (or rarefaction to rarefaction)

Parts of Longitudinal Waves Just like a transverse wave, longitudinal waves have period, frequency, wavelength, wave speed and they obey the equation v = f λ Just like in a transverse wave, the amplitude of a longitudinal wave is the largest distance a single particle travels measured from its rest position. It is difficult to see this is a “snap shot” of a longitudinal wave.

Examples of Transverse & Longitudinal Waves Transverse Waves Longitudinal Waves Electromagnetic (EM) Waves (Chp 14) Sound Waves (Chp 15) Surface Water Waves Seismic Waves (Earthquake waves) Waves on a String Matter waves (not in syllabus)

Comparison between Transverse and Longitudinal Waves Similarities: Both transfer energy without transferring matter (the particles do not move along with the wave) Both require vibrations Both have amplitude, wavelength, wave speed, period, frequency and obey the equation v = f λ Longitudinal waves can also be represented using wavefronts (represent compressions instead of crests)

Comparison between Transverse and Longitudinal Waves Differences: Transverse Waves Longitudinal Waves Wave direction is perpendicular to vibration direction Wave direction is parallel to vibration direction Crests and Troughs Compressions and Rarefactions Surface Water Waves, Waves on a string, EM Waves Sound waves, seismic waves

Summary Longitudinal Waves are waves direction of wave is parallel to direction of vibrations Compressions and Rarefactions Examples of Transverse and Longitudinal Waves Compare and contrast between transverse and longitudinal waves
