Sadržaj • Snelov zakon • Refrakcija • Refleksija • Optika • Prizme • Lenses • Svjetlost Description Explore bending of light between two media with different indices of refraction. See how changing from air to water to glass changes the bending angle. Play with prisms of different shapes and make rainbows. Primjeri obrazovnih ciljeva • Explain how light bends at the interface between two media and what determines the angle.
