- Please draw a ray diagram to locate the imageUsing the thin lens aanalysis, light entering a lens is assumed to be refracted a. at the right surface of the lens b. at the left surface of the lens O c. at the center of the lens d. at the edges of the lensThe Lens Equation If Fis the focal length of a convex lens and an object is placed at a distance x from the lens, then its image will be at a distance y from the lens, where F, x, and y are related by the lens equation FX y Suppose that a lens has a focal length of 4.8 cm and that the image of an object is 4 cm closer to the lens than the object itself. How far from the lens is the object?
- 4. Which term describes an image that is in the opposite orientation thar the object from which it was formed? virtual lateral erect inverted L8 a) The diagram shows two light rays that form an intermediate image by the objective lens an optical compound microscope. These rays are incident on the eyepiece lens. The focal points of the two lenses are marked. not to eyepiece lens scale objective lens to Draw rays on the diagram to show the formation of the final image. b) The object is viewed when the microscope is in normal adjustment. State what is meant by normal adjustment when applied to a compound microscope. c) The object O is placed at a distance of 24.0 mm from the objective lens and the final image is formed at a distance 240 mm from the eyepiece lens. The focal length of the objective lens is 20.0 mm and that of the eyepiece lens is 60.0 mm. The near point of the observer is at a distance of 240 mm from the eyepiece lens. Calculate the distance between the lenses.+ Mirror Equation: Si So M; = = - Yo So Principle Ray: the ray from object to mirror that is parallel to the principle (optical) axis will reflect in a path that intersects the image focal point. Radius Ray: the ray from the object whose path is aligned curvature center point will reflect directly back to the center point on the principle (optical) axis. Central Ray: the ray from the object whose path is directed towards the center of the mirror (intersection with the principle axis) will reflect from the lens in the opposite direction with respect the optical path.
