Pre Lab
This week's lab will explore waves (specifically waves on a string). When something happens, it takes time for the effects of that something to reach distant points. For example, when I throw a stone into a pond, it moves the water. The water near the stone moves right away, but the water far from the stone doesn't move immediately. The signal (energy) from the stone moves outward from the initial point as a wave. Waves are made up of peaks (crests) and low points (troughs). They are described by how far the peaks and throughs are from the rest position (amplitude), how fast they are moving (velocity), how many waves there are per second (wavelength), and the distance between crests (wavelength).
These factors are related mathematically as we will explore in lab. The videos to the right describe the relationships as well. There are also different types of waves, which we will discuss in class. That being said, waves always transfer energy.
In the lab this week we will explore properties of waves in a string. Specifically, we will 1) conduct a virtual lab using a Phet Simulation, 2) use Capstone and a wave generator to create waves in a string. Prior to lab please complete the following:

Lab
This week you will be completing the Waves on a String lab found your lab manual.
We will be using a Phet simulation, a harmonic oscillator (wave generator), and Capstone software to complete this lab.
