A thin lens bas surfaces with magnitudes of radii R1 = +5 cm and R2 = -3 cm. The lens is made of a material with an index of refraction of 1.5. If an object is placed 10 cm to the left of the lens where will the image be formed? What is the magnification? Is the image is real? Is the image inverted? Draw a ray diagram for this situation using at least two rays.
