Calculating the properties of the image
Equation is the same as for the curved mirrors!!!!
f: focal distance (distance from the focal point to the center of the lens) fɬ for converging lens, fɘ for diverging len
o: distance of object to the center of the lens (oɬ for real object, oɘ for imaginary objects)
i : distance of image to the center of the lens (iɬ for real images, iɘ for imaginary images)
m: magnification: size of image/size of object (mɬ image is erect, mɘ image is inverted)
d: diopters of the lens, d=1/f, if combining several lenses, the resulting lens will have d=d1+d2+d3+ …
