Extra Resources: Unit 2
Below is a review of the topics that will be covered in the Unit 2 Exam. Click on the link to download the pdf.
These simulations were created by teachers for the PhET Interactive Simulations Project at the University of Colorado at Boulder. Visit their site to see more simulations on Magnetism or Light & Radiation.
Magnetic Fields, Induction, and Generators
This applet can be used to visualize magnetic fields, the current induced in a circuit loop by a changing magnetic field, the magnetic field created by a current loop, and how to use these principles to create a generator.

Radiation Propagation
This online simulation shows how changing electric field lines propagate away from a moving charge. Go to the download page for more information or click on the image on the right to run the simulation. |
Radio Waves
This simulation shows how radio waves are broadcasted from one antenna to another. Go to the download page for more information or click on the image on the right to download the kit. |
Snell's Law
This applet illustrates how the path that light takes is bent when it passes through a barrier into a material with a different index of refraction. Go to the download page for more information or click on the image on the right to download the kit. |
Light and Water
This simulation shows how our view of objects gets distorted by the change in index of refraction between water and air. An undistorted image is created when viewed from inside the water, but the image is shifted when viewed above the water's surface. Total internal reflection can also be seen when the angle of incidence is too great when going from the water to air. You can go to the simulation website here. |
Geometric Optics
This simulation shows how the properties of a lens and the position of an object will change the image created. Go to the download page for more information or click on the image on the right to run the simulation. |
This TED-Ed Talk given by Adam Savage from MythBusters tells the stories behind several scientific discoveries, including how the speed of light was first measured.
