Splet24. jul. 2016 · A. The image and object have the same size only if they are at the same distance away from the center of a converging lens. Thus, if they are at different distances away from the lens center, they would have different sizes. In the case of a diverging lens, the object distance is greater than the image distance, and the magnification (size of ... Splet18. feb. 2015 · Knowing the size of object, would help calibrate the camera. Say a object which (in your case : ball) is say 5 cm in real world is represented using 30 pixels, then the distance between object which is 300 pixels on image can be calculate as (300 * 5 / 30). Thus knowing the object size is key factor if the plane containing the objects is variable.

an inverted image is magnified by 200% when the object is placed …

SpletBest answer Image with magnification -1 means image is inverted and of the same size. Therefore, object is at 2F and the image is also at 2F on the other side of the lens. Therefore, distance between the object and its image is 4f=60cm => f=15 cm Object distance 2f= 30 cm, if the object is shifted towards the lens by 20 cm, the new obiect … SpletThe distance from the center of the lens to the focal point is again called the focal length f of the lens. Note that the focal length and power of a diverging lens are defined to be negative. For example, if the distance to F in Figure 3 is 5.00 cm, then the focal length is f = –5.00 cm and the power of the lens is P = –20 D.
