The lens shown has radii 11.9cm and 23.5cm and is made of a material with index of refraction 1.53. Use the shape of the lens to assign the given radii and their signs (hint: which side looks more curved?). If an object is placed 19.6cm from the lens, what will be the position of the image? Give a positive or negative value for the image position, using the usual sign conventions for lenses
