When a man’s face is in front of a concave mirror of radius 100 cm, the lateral magnification of the image is + 1.5. What is the image distance?
Answer to relevant QuestionsA convex mirror in a department store produces an upright image 0.25 times the size of a person who is standing 200 cm from the mirror. What is the focal length of the mirror? A child looks at a reflective Christmas tree ball ornament that has a diameter of 9.0 cm and sees an image of her face that is half the real size. How far is the child’s face from the ball? For values of do from 0 to ∞, (a) Sketch graphs of (1) di versus do and (2) Mversus do for a converging mirror, (b) Sketch similar graphs for a diverging mirror. An object placed 30 cm in front of a converging lens forms an image 15 cm behind the lens. What are the focal length of the lens and the lateral magnification of the image? Using the thin lens equation and the magnification factor, show that for a spherical diverging lens, the image of a real object is always virtual, upright, and reduced.
