- A candle (ho = 0.34 m) is placed to the left of a diverging lens (f = -0.051 m). The candle is do = 0.14 m to the left of the lens. Numerically, what is the image distance, di in meters?One method of measuring the focal length of a lens is to form an image of an object that is many focal lengths away from the lens. Show from equation (1/f=1/o+1/i) that the image distance is approximately equal to the focal length when the object distance is very large (say, o=100f). What happens when the object distance become infinitely far away?A 2 cm high object is viewed through a diverging lens with a -12 cm focal length. If the object is 8cm from the lens, then realtive to the lens where is the image and what is its height?
- An object with a height of -0.06 m points below the principal axis (it is inverted) and is 0.200 m in front of a diverging lens. The focal length of the lens is -0.23 m. (Include the sign of the value in your answers.) (a) What is the image distance? (b) What is the magnification? (c) What is the image height?An object is placed 30 cm from the center of a 50-cm-focal-length converging lens. (a) Draw a ray diagram and show where the image is located. (Your diagram MUST be legible and correct to earn points). (b) Find the location of the image analytically using the thin lens equation. (c) What is the magnification? (Pay attention to the signs).A microscope objective with a magnification of 20 is used in a microscope with a magnification of 56. Find the focal length of the ocular if the ocular's image is formed at the eye's near point, 27 cm from the eye. Neglect the distance between the eye and the ocular.
