- Can an image be larger than the object even though its magnification is negative? Explain.arrow_forwardDuring LASIK eye surgery (laser-assisted in situ keratomileusis), the shape of the cornea is modified by vaporizing some of its material. If the surgery is performed to correct for nearsightedness, how does the cornea need to be reshaped?arrow_forwardIf the cornea is to be reshaped (this can be done surgically or with contact lenses) to correct myopia, should its curvature be made greater or smaller? Explain. Also explain how hyperopia can be corrected.arrow_forward
- Some telephoto cameras use a mirror rather than a lens. What radius of curvature mirror is needed to replace a 800 mm focal length telephoto lens?arrow_forwardExplain why a fish in a spherical goldfish bowl appears larger than it really is.arrow_forwardUse the law of reflection to prove that the focal length of a mirror is hall its radius of curvature. That is, prove that f = R/2. Note this is true for a spherical mirror only if its diameter is small compared with its radius of curvature.arrow_forward
- Will the focal length of a lens change when it is submerged in water? Explain.arrow_forwardIf a concave mirror produces a real image, is the imagenecessarily inverted? Explain.arrow_forwardObtaining a large spherical mirror with a focal length of 0.654 m from the Physics Storeroom, Mr. H takes his last period class outside for a fascinating demo. A student volunteer holds the mirror at an angle such that the face of the mirror is directed towards the Sun - roughly 1.46x1011 m away. Mr. H then uses a piece of paper with George Washington's picture on it to focus the image of the sun on the sheet of paper. Before the paper engulfs in flames, a bright image of the sun can be seen on the paper. Use the mirror equation to calculate the distance from the mirror to the image of the sun.arrow_forward
- If a lens is immersed in water, its focallength changes, as discussed in Conceptual Example 26-17.(a) If a spherical mirror is immersed in water, does its focal lengthincrease, decrease, or stay the same? (b) Choose the best explanation from among the following:I. The focal length will increase because the water will causemore bending of light.II. Water will refract the light. This, combined with the reflection due to the mirror, will result in a decreased focal length.III. The focal length stays the same because it depends on thefact that the angle of incidence is equal to the angle of reflection for a mirror. This is unaffected by the presence of thewaterarrow_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
