You hold a magnifying glass up to a flower. The magnifying glass has a focal length of 6.0 cm and you hold the flower 4.0 cm from the glass. What is the distance from the glass that you see the image? What is the magnification? Use a scaled ray tracing diagram! Focal point Virtual image Object
A magnifying glass is a single convex lens with a focal length of ff = 13.0 cm . What is the angular magnification when this lens forms a (virtual) image at the person's near point (assumed to be 25 cm)? M =
