Document Summary

*the overlap of two identical waves traveling in opposite directions. *the superposition of two travelling waves (opposite directions) creates a standing wave. *overlap of two waves having: the same frequency, wavelength and amplitude, but different in speed, move in the same directions. *two wage can pass through each other without altering either wave in any way. = Two string, one thick and one thin, are connected to form one long string. A wave pulse travels along the sting and passes the point where the two strings are connected. *tension is constant: it is one connected string. *mass density will change: thicker portion has more mass -> greater linear mass density. *speed will change: tension should be the same. *amplitude will change: lighter rope will move more. *frequency will not change: rope still wiggles at same frequency. *wavelength will change: if speed decrease, so does because c = f.
