Final answer:
Physics principles involving lenses and magnification are used to find the image distance, magnification, and size of a magnified image when using a magnifying glass.
Step-by-step explanation:
The question involves determining the image location, its magnification, and the size of the magnified image in the context of using a magnifying glass. It falls under the subject of optics within Physics. To find these properties, we can use lens equations and magnification concepts. For instance, to calculate the image distance (di), we can use the lens formula 1/f = 1/do + 1/di, where f is the focal length and do is the object distance. The magnification (m) of the lens is calculated using the equation m = -di/do. Lastly, if you know the magnification, you can find the size of the magnified image using the calculation hi = h x m, where h is the original size of the object, and hi is the size of the image.
