00910.0pointsAn object isp= 38.2 cm in front of a concavemirror. Its real image height is 5 times largerthan the object height.phWhat is the radius of curvature of the mir-ror?Answer in units of cm.01010.0pointsA concave mirror with a radius of curvatureof 1.7 m is illuminated by a candle located onthe symmetry axis 3.7 m from the mirror.Where is the image of the candle?Answer in units of m.01110.0pointsIf the speed of light through material Z is2.5×108m/s, what is this material’s index ofrefraction? The speed of light in a vacuum is3×108m/s.01210.0pointsDiamond has a high index of refraction atabout 2.4, which helps account for its sparkle.How fast does light travel through a dia-mond?The speed of light in a vacuum is3×108m/s.Answer in units of m/s.013(part1of2)10.0points
