Characteristics of Waves Online Lab _______________________

Name

6-MS-PS4-1: Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave and how the frequency and wavelength change the expression of the wave

In this lab you will investigate the characteristics of a wave and how those characteristics are related and change in magnitude depending on the energy of the wave by examining water waves. All waves have common measurable characteristics, amplitude, wavelength and frequency.   

Wavelength is measured from a crest to a crest or a trough to a trough. Use the grid on the graph. Count the boxes to measure a wavelength. Amplitude is the height of a wave. Use the 0 line at the water’s surface and count boxes going up or down on the grid to determine amplitude. Frequency measure how many waves cycles pass a point at a given time. The Step button will help you determine frequency. Get a full set on the grid (from one end to the other) and divide the seconds by the number of crests.
