- Can an image be larger than the object even though its magnification is negative? Explain.arrow_forwardWill the focal length of a lens change when it is submerged in water? Explain.arrow_forwardExplain why an object in water always appears to be at a depth shallower than it actually is? Why do people sometimes sustain neck and spinal injuries when diving into unfamiliar ponds or waters?arrow_forward
- A student makes a microscope using an objective lens and an eyepiece. If she moves the lenses closer together, does the microscope’s magnification increase or decrease? Explain.arrow_forward2. In most applications of concave spherical mirrors (including this activity) it is assumed that all light rays travelling parallel to the mirror's optical axis are reflected through the mirror's focal point; however, this is an approximation that applies only to light rays traveling near the mirror's optical axis. Explain why a concave spherical mirror does not reflect all light rays travelling parallel to its optical axis through its focal point.arrow_forwardA cataract-impaired lens in an eye may be surgically removed and replaced by a manufactured lens. The focal length required for the new lens is determined by the lens-lo-retina distance, which is measured by a sonar-like device, and by the requirement that the implant provide for correct distance vision. (a) If the distance from lens to retina is 22.4 mm, calculate the power of the implanted lens in diopters. (b) Since there is no accommodation and the implant allows for correct distance vision, a corrective lens for close work or reading must be used. Assume a reading distance of 33.0 cm, and calculate the power of the lens in the reading glasses.arrow_forward
- What is the focal length of a makeup mirror that produces a magnification of 1.50 when a person’s face is 12.0 cm away? Explicitly show how you follow the steps in the ProblemSolving Strategy for Mirrors.arrow_forwardPhysics An object 1.1 cm high is viewed under a magnifier of focal length 9.0 cm by a person with a near point of 28 cm and a far point of ∞. (a) Find the angle subtended by the image formed by the magnifier when the eye is relaxed. (b) Find the angle subtended by the image formed by the magnifier when the eye is focused at its near pointarrow_forwardHow could you very quickly make an approximate measurement of the focal length of a converging lens? Could the same method be applied if you wished to use a diverging lens? Explain.arrow_forward
- confused on whether i use the given vectors or if i have to calculate the vectors using the image givenarrow_forwardA near-sighted person might correct his vision by wearing diverging lenses with focal length f� = -40 cmcm . When wearing his glasses, he looks not at actual objects but at the virtual images of those objects formed by his glasses. Suppose he looks at a 13-cmcm-long pencil held vertically 1.5 mm from his glasses. Use ray tracing to determine the location of the image. Express your answer with the appropriate units. Enter positive value if the image is on the other side from the lens and negative value if the image is on the same side. Use ray tracing to determine the height of the image. Express your answer with the appropriate units.arrow_forwardYou have learnt that plane and convex mirrors produce virtual images of objects. Can they produce real images under some circumstances?
