1) The condenser lens concentrates light and makes illumination of image more uniform. 2) The bending of light is also known as refraction. 3) Total magnification = ocular lens magnification x objective lens magnification. 4) The total magnification of an image is 1200x and the magnification of the ocular lens is 10x. What is the magnification of the objective lens? Y = objective lens 1200x = 10x X y 1200x / 10x = y y = 120x Objective lens magnification = 120x 5) The limit of resolution
