WebOct 26, 2024 · Gestalt laws explore the way people tend to perceive a whole object rather than a sum of its parts. One of these rules is the law of closure. This particular principle of the Gestalt approach states that if a figure has a gap in its form, people still perceive it as a complete and closed figure (Foley & Matlin, 2010).

WebLenses are found in a huge array of optical instruments, ranging from a simple magnifying glass to the eye to a camera’s zoom lens. In this section, we use the law of refraction to explore the properties of lenses and how they form images. Some of what we learned in the earlier discussion of curved mirrors also applies to the study of lenses.
