Phys. Science Chapter 17 Wavelength Problems
(Do not write on this sheet) Show the set up in the equation for each problem
Wavelength is the distant from crest to crest of a wave. Period is the time for 1 complete wave.
Speed is how quickly the wave is moving often in meters/second
Frequency is the number of complete waves in a given time often in Hertz (Hz).
