Imaging Using Wave Theory,heory we assume that Huygens’wavelets emerge from each point of the object and travel to the lens. The lens produces the diffraction pattern of the object in its focal plane, which may be seen as the Fourier transformation of the object pattern. The lens also produces the image of the object by refrArroyo 发表于 2025-3-25 10:24:33

Geometrical Optics,al image of a real object, produced by a positive thin lens. Cones of light are assumed to diverge from each object point to the lens. There the cones of light are transformed into converging beams traveling to the corresponding real image points.choroid 发表于 2025-3-25 21:02:36

Trees planted in the right place around buildings can improve air conditioning and heating costs by providing shade or by affecting wind speed or direction.
