The focal length of convex tens is `f` and the distance of an object from the principal focus is x. The ratio of the size of the real image to the size of the object isA. `((f+x))/(f)`B. `(f)/(x)`C. `sqrt((f)/(x))`D. `(f^(2))/(x^(2))` |

Answer» Correct Answer - B `(v)/(u)=(f)/(u-f)` `= (f)/("distance of object from focus")=(f)/(x)`. |
