where n is an integer, λ is the wavelength of the light the zone plate is meant to focus and f is the distance from the center of the zone plate to the focus. When the zone plate is small compared to the focal length, this can be approximated as r n ≃ n λ f {\displaystyle r_{n}\simeq {\sqrt {n\lambda f}}}
Visual sociology attempts to study visual images produced as part of culture. Art , photographs , film , video , fonts , advertisements , computer icons , landscape , architecture , machines , fashion , makeup , hair style , facial expressions , tattoos , and so on are parts of the complex visual communication system produced by members of ...

Sociology – the study of society [1] using various methods of empirical investigation [2] and critical analysis [3] to understand human social activity, from the micro level of individual agency and interaction to the macro level of systems and social structure.
Exposure latitude is the extent to which a light-sensitive material can be exposed (overexposed or underexposed) and still achieve an acceptable result. [1] It is relevant to both digital and analogue processes such as photolithography and photography .
Immersion lithography is a technique used in semiconductor manufacturing to enhance the resolution and accuracy of the lithographic process. It involves using a liquid medium, typically water, between the lens and the wafer during exposure.
Sociological images was founded in 2007 by sociology professor Lisa Wade (Occidental College) and hosted at Blogspot to share ideas and teaching resources with other faculty teaching about sociology. Six professors were invited to serve as the foundational bloggers.
