Study Notes

Luminous and Non-Luminous Objects

Luminous objects emit their own light
Examples include: stars, light bulbs, fire, lightning
Non-luminous objects reflect light from an external source
Examples include: Moon, planets, buildings, most objects around us

Transparent, Translucent, and Opaque Objects

Transparent objects: Light passes completely through them, allowing objects on the other side to be clearly seen
Examples: clear glass, clean water, clean air
Translucent objects: Light passes through them, but not completely, so objects on the other side are not clearly visible
Examples: trace paper, frosted glass, muslin cloth
Opaque objects: Light does not pass through them; they block the view of objects on the other side
Examples: wood, metal, cardboard
