- Electromagnetic Spectrum - In this applet, you can click on the wavelength/frequency scale and change the wavelength and frequency by dragging the mouse or by using the arrow keys on the keyboard. Holding the shift key down while pressing the left or right arrow keys changes the wavelength by a factor of 10.
- Electromagnetic Wave - This animation (java applet) shows an electromagnetic wave, namely a plane polarized wave, which propagates in positive x direction.

- The mathematics of refraction - Snell's law
- Boundary Behavior - the concepts behind the math known as Snell's law
- Snell's law Java applet from Northwestern University - manipulate the variables on both sides of the boundary, and see a wave front view or a laser view
- Refraction and Reflection - change the indices of refraction of the two media, and drag the incoming ray to any angle between 0 and 90 degrees

- Beat Frequencies in Sound - A beat frequency or beat wave is a sound of fluctuating volume caused when you add two sound waves of slightly different frequencies.
- Beats - a java applet to investigate this sound phenomenon
- Boundary Behavior - the concepts behind the math known as Snell's law
- Diffraction of Light by a Single Slit - an applet to investigate diffraction
- Hearing Subtraction - an activity on beats and frequency
- Index of wave terms - good diagrams accompany each definition

- Refraction and Reflection - change the indices of refraction of the two media, and drag the incoming ray to any angle between 0 and 90 degrees
- Standing Wave - Explanation by Superposition with the Reflected Wave
- Snell's law Java applet from Northwestern University - manipulate the variables on both sides of the boundary, and see a wave front view or a laser view

- Electromagnetic and visible spectra
- Light absorption, reflection, and transmission - this tutorial includes practice questions
- Form white light by adding three colors of light using a click and drag applet
- Color addition - two questions to check understanding conclude this tutorial
- Color subtraction - examples are followed by a series of questions to check understanding
