Light and Optics (2) (Science)

Light travels in straight lines, bounces off surfaces, bends and separates as it passes through materials, and separates into different colors. Experiments in this book use familiar objects such as mirrors, marbles, and thermometers to illustrate concepts including reflection, refraction, and infrared light.
