|
Magnification = Strength of lens/ image size
|
|
|
Magnification = image size/ real size
|
|
|
Magnification = image size x real size
|
|
|
Magnification = real size/ image size
|
Detailed explanation-1: -Magnification = scale bar image divided by actual scale bar length (written on the scale bar).
Detailed explanation-2: -The ratio of the height of an image ( ) to the height of an object ( ) is defined as the magnification of a lens. Also, magnification is equal to the ratio of image distance to that of object distance. The formula is m = h i h o .
Detailed explanation-3: -Let’s explore the magnification formula (M= v/u) for lenses and see how to find the image height and its nature (whether it’s real or virtual).
Detailed explanation-4: -An object’s magnification is generally given by the equation M = (hi/ho) =-(di/do), where M = magnification, hi = image height, ho = object height, and di and do = image and object distance.
