Questions about the Light and Shadows poster

What’s on the Light and Shadows poster?

A definition and 6 facts worth remembering. Light travels in straight lines from a source. A shadow is simply the space light could not reach. Light travels in straight lines until something changes its path.; Opaque objects block it completely — a sharp shadow.; Translucent objects let some through — a faint shadow.; Transparent objects let it nearly all through — almost no shadow.; Reflection bounces light off a surface at the same angle it hit.; Refraction bends light as it passes into water or glass.; A straw looks broken in a glass of water. That is refraction, not a broken straw.. Move the source closer and the shadow gets bigger. Move the object closer to the wall and it gets sharper.

When should you use the Light and Shadows poster?
