The Skinny on Lenses +si = −m = inverted image = real image −si = +m = upright image = virtual image Converging lenses produce b ...
So the image is located 40 cm from the lens, on the opposite side from the object. Because si is positive, the image is real. R ...
Here’s How to Crack It With so = 48 cm and f = −24 cm, the lens equation gives us: The image is 16 cm from the lens, on the sa ...
