In this movie, you’ll learn about the kind of energy that helps us see: light! Did you know light is made up of tiny particles that travel in waves? When light hits an object, it reflects, or bounces off the object and into our eyes so we can see it. The object also absorbs, or takes in some light. Light can easily pass through transparent, or clear objects, but it cannot pass through opaque objects. Light bounces off translucent objects in many directions. How does light cause shadows?
