How things wave Introduction to WAVES. So - Waves.....   We spoke about energy.  Energy can, as it turns out, travel in waves.  In fact, you can think of a wave as a traveling disturbance, capable of carrying energy with it.  For example, light "waves" can have energy - like solar energy.  Ocean waves can certainly carry energy.   There are several wave characteristics (applicable to most conventional waves) that are useful to know: amplitude  - the "height" of the wave, from equilibrium (or direction axis of travel) to maximum position above or below crest  - peak (or highest point) of a wave trough  - valley (or lowest point) of a wave wavelength (lambda - see picture 2 above)  - the length of a complete wave, measured from crest to crest or trough to trough (or distance between any two points that are in phase - see picture 2 above).  Measured in meters (or any units of length). frequency (f)  - literally, the number of comp

Doppler effect

Doppler! The Doppler Effect First, some animation: http://www.lon-capa.org/~mmp/applist/doppler/d.htm http://falstad.com/ripple/ So above, the blue dot is emitting sound and moving to the right.  Since it is moving AND emitting sound at the same time, the waves are getting closer on the right - resulting in a shorter wavelength (or higher frequency).  And it is the complete opposite on the left. http://falstad.com/ripple/ Play with this and choose the "Doppler Effect 1" example. And for some more visuals: https://highered.mheducation.com/olcweb/cgi/pluginpop.cgi?it=swf::800::600::/sites/dl/free/0072482621/78778/Doppler_Nav.swf::Doppler%20Shift%20Interactive The key in the Doppler effect is that motion makes the "detected" or "perceived" frequencies higher or lower.   It's worth noting that the effect also works in reverse. If you (the detector) move toward a sound-emitter, you'll detect a higher frequency. If you
