Use the lens equation to deduce algebraically the following: "An object placed within the focus of a convex lens produces a virtual and enlarged image" |
|
Answer» Solution :`1/v - 1/U = 1/f " or "1/v = 1/f + 1/u` convex lens :f > 0, u < 0 (object on the left) For 0 < | u | < f ` 1/v = 1/f - (1)/(|u|)LT 0 "" i.e. ULT 0 `(image on left , virtual) Also for the case , ` (1)/(|u|) lt (1)/(|u|) i.e. |u| lt| v |`(image enlarged ) |
