Every once in a while we come across something that has the chance to make a real difference in the classroom in both engaging the students and making your life as a professor a little easier. We think this may be one of those times. Ripple tanks are such a wonderful way to teach your [...]

Refraction and Total Internal ReflectionStudents will be able to observe that refraction (bending) always takes place at the interface between two different transparent materials and that the angle of refraction in plastic is smaller than the angle of incidence in air. The light is directed at the center of the semicircular cup where it is [...]

Students investigate images formed by converging lenses using the Light Box and Optical Set, and discover the Focal Point.

The Law of Reflection states that the angle of incidence is equal to the angle of reflection. Students will use ray tracing to predict the location and image characteristics for flat and curved mirrors. Students will use ray tracing to discover and explain how different types of images are created with plane, concave and convex mirrors

PurposeIn this activity, students will investigate the behavior of light as it passes from one transparent material to another.
Discussion
When light passes from one transparent material to another, it undergoes refraction. If the light crosses the boundary between the materials at an angle, the light changes direction. In this activity, you will see how the direction [...]

One day in my classroom...“My students were amazed by examples of colorful fiber optics but didn't understand how the light goes from one end to the other; even when bent. After testing various angles of laser light through water and air up to 40 degrees, most students assume the light will continue to exit the other side.
