Resources Needed: 

Your Task: 

There are 6 interactive activities listed below. Click the links below to explore the Electromagnetic Spectrum.

Activity 1: Visible Light

Part A

  Go to  Virtual Prism

   Click on hand, move back and forth, hold down button for white light.
  (Note that a prism separates light into various wavelengths)

Part B

Go to: BrainPop and click on Electromagnetic Movie

Listen to movie, then take quiz.(remember you may be tested on this information at a later date)
Click on "Experiment with Bob the E-Labrat" (on the BrainPop site)

Materials needed for Experiment

1. sunny day

2. sheet of white paper 

3. a pan of water

4. a mirror

Activity 2: What ARE Electromagnetic Waves?

Go to this interactive site for background knowledge on electromagnetic waves.

Electromagnetic Waves?

For an interactive Demonstration of an X-Ray machine


Activity 3: The Electromagnetic Spectrum


Go to Java Applet

In this applet, you can click on the wavelength/frequency scale and change the wavelength and frequency by dragging the mouse around. You can also change the wavelength by using the arrow keys on your keyboard. Holding the shift key down while pressing the left or right arrow keys changes the wavelength by a factor of 10.
