The role of diaphragm is to vary the amount of light passing through the aperture.

The aperture ring changes the lens aperture which controls how much light reaches the film or digital sensor. A large aperture f/1.4 to f/2.8 = lots of light, fast shutter speeds, narrow depth of field A small aperture f/9+ = much less light, slower shutter speeds, wide depth of field
When a small aperture setting is used, such as f/11, a large depth of field will be achieved. One would use this, say, if they wanted to take a landscape photograph, and have most of the photo in focus. When a medium aperture setting is used, such as f/4, less of the photograph will be in focus, but not as much as if one were to use an aperture setting of f/1.8. A medium setting like f/4 could be used for a group photo. When a large aperture setting is used, such as f/1.8, a very small slice of the photograph will be in focus (shallow DOF.) This large aperture setting could be used for plant photography, macro photography, insect photography, etc.
The f-number is indicative of aperture. The smaller the number, the larger the aperture is, and the more light is let in. The Depth-of-Field is also reduced with a smaller f-number. f/1.7 is a very large aperture, and there will be little depth of field, but lots of brightness.
it must be very large

An aperture membrane is a section of enzine forming the base of an aperture.
small aperture= short focal range (this means less of the picture will be in focus...sounds like a bad thing but creates more artistic photos with blurry background and sharp subjects) large aperture= long focal range (objects far and close will remain in focus)
"Aperture" means "opening".
Large plate tectonics or the fossils had wings.
