Light travels in straight lines from a source, and objects in its path will either allow light to pass through completely (transparent), partially (translucent), or block it completely (opaque). Transparent objects like clear glass and water allow all light to pass through, translucent objects like frosted glass and plastic bags allow some light, and opaque objects like books and cardboard block all light.
