Using the magnification equation m = - v / u. The image should be 13.73 mm in front of the lens
The rays of light going through the dead centre are not deviated. So the angle from the top of image to lens centre is the same as for top of object to lens centre. So height is proportional to distance. So 13/51 = 3.5/dist giving distance=3.5x51/13 = about 13.73mm
The relation between the distance and height of an object and the image goes like this:L1/H1=L2/H2where L1 and H1 is the Length of the object from the lens and H1 is the height of the object respectively. Same goes for L2, H2 except these are for the image of the same object.If you put values in the above formula, the distance of the image from the lens comes out to be 13.73mm
The Vinson Massif mountains are located in Antarctica and are approximently 4,897 m which in feet is, 16,850 feet.
Mountains are beautiful and can reach wonderful height. Mount Lhotse II is located in Nepal, and is 26,723 feet tall.

An object is located 51mm from a diverging lens the object has a height of 13mm and the image height is 3.5mm?Diverging lens do not form real images.When parallel rays of light passes thru a diverging lens, the rays diverge (spread apart) on the other side of the lens. It forms a virtual image. The object will look smaller.The image is on the same side of the lens as the object, so f is negative.Do = 51mm Ho = 13mmDi = ______ Hi = 3.5mmDi = -13.7mm1/Di + 1/Do = 1/f1/-13.5 + 1/51 = 1/ff = -18.36 mm

13.7 millimetersThis answer is correct, but the formula is most important.The formula is:Hi = height of imageHo = height of objectSi = Distance of image from lensSo = Distance of object from lensYou are trying to find Si, so that is your unknown.Here is your formula: Hi/Ho = Si/SoOr in this case: 3.5/13 = Si/51The rest is basic algebra.Good luck!You can use the ratio equation; (Image Height)/(object height) = - (image location)/(object location) In your case you will get a negative location which means the image is on the same side of the lens as the incoming light.
hi/ho = di/do di = dohi/ho di = (51mm)(3.5mm)/(13mm) di = 14mm * rounded to 2 significant figures The image would be 14mm in front of the lens.
Using the expression v/u = Image size / object size we can find the value of v. v = 15 * 3.5/13 = 4 (nearly) So approximately at a distance of 4 mm in front of the lens the image is located on the same side of the object.
The rays of light going through the dead centre are not deviated. So the angle from the top of image to lens centre is the same as for top of object to lens centre. So height is proportional to distance. So 13/51 = 3.5/dist giving distance=3.5x51/13 = about 13.73mm
