Reflection and Refraction
Reflection and Refraction

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...

Images Produced by Curved Mirrors
Images Produced by Curved Mirrors

Students use the Light Box and Optical Set's two different curved mirrors to investigate how light reflects from concave mirrors. Students make predictions and observations, and make generalizations about the focal point of a mirror, depending on its curvature. Download...

Lab #29.3 Light: Mirror, Mirror on the Wall

Purpose In this activity, students will investigate the minimum size mirror required for you to see a full image of yourself. Discussion Why do shoe stores and clothier shops have full-length mirrors? Need a mirror be as tall and wide...

Reflection & Refraction
Reflection & Refraction

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...
