Unit 3: Waves and Light Lesson 4: Interactions of Light • How does matter transmit light? 1. Transparent: mediums that allow light to completely travel through it; for example-glass, water, and air 2. Translucent: mediums that allow some light to pass through in many different directions; for example-frosted glass, shaded lamps and tissue paper Unit 3: Waves and Light Lesson 4: Interactions of Light • What kind of matter can light absorb? 1. Opaque: does not let any light pass through causing light to either be reflected or absorbed; for example-wood, metal, brick, dark colored clothing Unit 3: Waves and Light Lesson 4: Interactions of Light • We see specific colors when an object reflects that specific color and is reflected into our eyes. (opaque) • When an object reflects every color, the object appears white. • When an object absorbs every color, the object appears black. • When it comes to transparent or translucent objects we see the color being absorbed rather than the color being reflected. Unit 3: Waves and Light Lesson 4: Interactions of Light • How does a medium affect the speed of light waves? • What wave interaction influences the direction of light? • How does the direction of light change with refraction?
