Flashcards

Light: A form of energy that travels in straight lines and allows us to see
Shadow: A dark area formed when an opaque object blocks light
Transparent: Allows light to pass through clearly — example: clear window glass
Translucent: Allows some light through but scatters it — example: frosted glass
Opaque: Blocks light completely — example: wood, brick, your hand
Reflection: Light bouncing off a surface — mirrors have very smooth reflective surfaces
Light source: An object that produces light — the Sun, a lamp, a candle
Natural light: Light produced by nature — sunlight, fireflies, lightning
Artificial light: Light made by humans — lamps, flashlights, streetlights
Rainbow: Colorful arc of light formed when sunlight passes through water droplets
Absorption: When a material takes in light instead of letting it through or bouncing it back
Refraction: When light bends as it moves from one material to another — makes rainbows!
