  1. 1. Science Starter : February 9, 2012 <ul><li>The speed of a waves equals its wavelength times its amplitude . </li></ul><ul><li>Wavelength measures the distance from one wave crest to the next. </li></ul><ul><li>The number of wavelengths passing a point in a given time is a wave’s amplitude . </li></ul><ul><li>As the frequency of a wave increase, its wavelength increases . </li></ul>Write out the statement. If it is true leave it alone, if it is false change it to make it true . BE SURE TO WRITE THE DATE
