Introduction to Wave Motion Callie De. May
We are surrounded by waves…
Ocean Waves
Earthquakes
Slinky’s
Light Waves
What does a wave look like? ? ? Well…that depends… What type of wave are you talking about? You mean…there are different types of waves? !? !
YES! There are three main types of waves
Type 1: Transverse Waves
Parts of the Transverse Wavelength (λ) node crest amplitude trough Direction of oscillation Direction of energy travel
Type 2: Longitudinal Waves
Parts of the Longitudinal Waves Compression Expansion Direction of travel Wavelength (λ) Movement of molecules
Type 3: Surface Waves Combination of Longitudinal and Transverse Waves
Although all types of waves can be studied in physics… There a few that mean more to us than others… And those are… Sound Waves and Electromagnetic Waves
Sound Waves • Longitudinal Wave • Produced by Oscillating object • Variety of Frequencies • Not capable of traveling through vacuum
Electromagnetic Waves • Transverse Waves • Can travel through vacuum • Electric and Magnetic Components • Spectrum defines different EM waves…
Electromagnetic Wave Spectrum Gamma rays X-rays Ultraviolet The type of EM wave depends on 1. Amount of Energy 2. Size of Wavelength Infrared Radio waves
In Conclusion… Waves are around us…everywhere… From the BIG… To the small… And everywhere in between!
