WebMay 4, 2005 · Hey all, I recently did an experiment using a diverging or convex lens, to produce different images according to the focal point. For the experiment I found the focal length, and set up the lens and light source at that distance. I used just paper for a screen to produce the real images created. WebFeb 18, 2024 · The thin lens equation is the same as the mirror equation and is written as 1 / f = 1 / d i + 1 / d o where: f is the focal length of the lens. d i represents the image distance. d o...
WebMar 1, 2024 · The Lens formula is: \frac {1} {f}=\frac {1} {v}+\frac {1} {u} according to the Convex Lens equation. It links a lens’ Focal Length to the distance between an object in front of it and the picture created by that item. The ratio of image length to object length is known as lens magnification.

WebThe focal length of a concave mirror is also negative That would give us -1/f = -1/v -1/u which is the same as 1/f = 1/v + 1/u. So,the thin lens formula works for both convex and concave lens. ( 1 vote) Flag Shresth 2 years ago 8:31
Web1/f = 1/v + 1/u. 1/f = 1/v + 1/-u. 1/f = 1/v - 1/u. We apply sign convention to make the equation obtained by similarity of triangles to make it general. as the signs for f and v are opposite with respect to concave mirror and convex lens the difference arises. Now try out for the magnification formula as well. citizens bank west view giant eagleWebSep 12, 2024 · We want to find how the focal length F P (denoted by f) relates to the radius of curvature of the mirror, R, whose length is (2.3.1) R = C F + F P. The law of reflection tells us that angles ∠ O X C and ∠ C X F are the same, and because the incident ray is parallel to the optical axis, angles ∠ O X C and ∠ X C P are also the same. dickey roberts child star sound trackWebCamera lens focal lengths are usually specified in millimetres (mm), but some older lenses are marked in centimetres (cm) or inches.
