This comprehensive kit introduces students to the properties of light and enables them to investigate how mirrors, lenses, and prisms alter light's path. Through 16 exercises, students measure angles of incidence and refraction, calculate refractive index, determine focal length, study concave and convex lenses and mirrors, compare real and virtual images, draw ray diagrams, polarize light, perform color additions and subtractions, split white light into the visible spectrum, and more.
