Final answer:
Examples of real-world prism-shaped objects include binoculars and photographic prisms, where prisms are used to direct light via total internal reflection and create continuous or line spectra.
Step-by-step explanation:
Real-world objects that are in the shape of a prism include binoculars and certain types of camera lenses. For example, binoculars utilize corner reflectors (prisms) with total internal reflection to direct light to the observer's eyes, allowing for magnified vision. A common type of prism seen in binoculars and camera lenses is a triangular shape, which is used for light dispersion and to create a continuous spectrum when light is passed through it.
A second example is a photographic prism, used to invert or revert an image for the correct orientation when observing or capturing images through the camera. It manipulates light rays similarly to those in binoculars, utilizing the refractive properties of prisms to adjust the direction of light traveling through the lens system.
