Additive color mixing shows how different colors of light combine to make another color. This is how computer monitors and color TVs make their colors.

In this lab, you can explore what happens when polarized light passes through an optically active material - that is the object labeled as the filter above. An optically active material is made up of chiral molecules - the molecules has a spiral shape.

In this lab, you can explore what happens when unpolarized light, with an intensity of 800 W/m2 is incident on a sequence of three polarizers. The light is traveling in the +x direction and the polarizers are located at x = 10 cm, x = 20 cm, and x = 30 cm.

This is a simulation of what happens when polarized light with an intensity of 800 W/m2 is incident on a polarizer. The light is traveling from left to right.

In this lab, you can explore the concept of the Doppler shift for electromagnetic waves. At the top is a simplified version of the emission spectrum from the Sun.

This lab shows a solar sail - a satellite or space probe that uses the radiation pressure of sunlight, reflecting from its sails, as its form of propulsion. The solar sail starts from rest at the same distance from the Sun that the Earth is.

This lab shows a plane-polarized electromagnetic wave that is traveling in the +z direction. One color is for the electric field vectors and the other color is for the magnetic field vectors.

This lab shows several representations for a series RLC circuit. The impedance triangle is shown at the top right. At the bottom left is the voltage vs.

In this lab, you can explore the impedance triangle for a series RLC circuit. The impedance (Z) of the circuit is the hypotenuse of the triangle. The resistance is the horizontal side of the triangle.

In this lab, you can explore an electric generator, which at its heart is simply a conducting loop rotating in a magnetic field. In this case, the field is uniform and directed into the page.
