WebbA pinhole camera, also known as camera obscura, or "dark chamber", is a simple optical imaging device in the shape of a closed box or chamber. In one of its sides is a small hole which, via the rectilinear propagation of light, creates an image of the outside space on the opposite side of the box. History *. Images created via a small opening ... WebbThe optimum size of the pinhole for the sharpest possible image occurs when the spread due to diffraction equals the spread due to the geometric effects of the pinhole. Estimate the optimum size of the pinhole if the distance from the pinhole to the film is 9.6 cm and the wavelength of the light is 539 nm. Show transcribed image text Expert Answer

WebbA conventional camera obscura uses a flat mirror that is an inch or two wider than the lens diameter and also about 1.5 times longer than its width. The difference between length and width is cause by the need to place the mirror at 45° to the lens optical axis. For example, a lens of 6-inch diameter would require a flat mirror of about 7×10 ...
