A double concave thin lens has surfaces with radius of curvature of magnitude 4 cm and 6 cm respectively. This diverging lens has a focal length of 4.8 cm. (i) What is the index of refraction for this lens? What is the position, magnification, and character (inverted/upright; virtual/real) of the image for an object located (ii) 3 cm from the lens? (iii) 10 cm from the lens? (iv) Draw the ray diagram for (ii) or (iii).
