An object of height 5.0 mm is placed 35.0 cm from the vertex of a spherical surface of a glass rod. An image is formed inside the rod 50.0 cm from the vertex of the glass rod. The refractive index of the glass is 1.5. (a) State two characteristics of the image (b) Determine the radius of curvature of the spherical surface of the glass rod (c) Sketch the ray diagram to show the formation of the image
