In Light Waves, David A. Adler helps children explore how light travels, bends, reflects, and makes the world visible. With clear explanations, everyday examples, and simple experiments, the book gives children a way to investigate ideas that may feel invisible at first but become real through play and observation. Anna Raff’s illustrations keep the topic approachable and lively. This title pairs well with Kodo materials that invite children to explore reflection, shadow, color, transparency, and the ways light changes as it moves through different spaces and materials.
