WebDiverging lenses are thicker at the center than they are at the edges. If the bottom half of a diverging lens is covered, then the bottom half of the image will not be visible. Diverging lenses only produce virtual images. Diverging lenses can produce images which are both magnified and reduced in size. Diverging lenses only produce upright images. WebTwo lens system – Image distance and magnification. Two converging lenses, with the focal length f 1 = 10 cm and f 2 = 15 cm are placed 40 cm apart, as shown on the figure. …
Web15 dec. 2024 · 1/F = 1/d + 1/f; 1/f = 1/F - 1/d; f = dF/ (d - F) = (- 16cm· 41cm)/ (41cm + 16cm) = - 11.5 cm. So image will be imaginary, distance from lens by 11.5 sm. Magnification … WebA concave lens is a lens that diverges a straight light beam from the source to a diminished, upright, virtual image. It can form both real and virtual images. Concave lenses have at least one surface curved inside. A concave lens is also known as a diverging lens because it is shaped round inwards at the centre and bulges outwards through the ...
