1. Using rays diagram (drawn to scale using pencil/ruler to get any credit) find the image (nature and position) of an object located 100 cm in front of a 60 cm focal length converging lense.
2. Using the lenses equation, calculate the exact position of the image and describe its nature appropriately using sign convention.
