Which one of the following statements is true concerning the focal length of a lens? O The focal length is different for different colors because of reflection. O The focal length is the same for all colors. O The focal length is different for different colors because of dispersion. O The focal length is different for different colors because of polarization. O The focal length is different for different colors because of spherical aberration.The bending of light as it moves from one medium to another with differing indices of refraction is due to a change in what property of the light? O speed O frequency O color O amplitude O periodA converging lens with a focal length of 12 cm produces a 3-cm high virtual image of a 1-cm high object. Which entry in the table below is correct? image distance location of image O 24 cm opposite side of lens from object O 8 cm opposite side of lens from object O 12 cm opposite side of lens from object O 8 cm same side of lens as object O 24 cm same side of lens as objectA ray of light propagates in water (n = 1.333) and strikes a sheet of crown glass (n = 1.523). If the angle of refraction in the glass is 35.29, determine the angle of incidence. O 32.80 O 41.20 O 35.20 O 45.0 O 30.30
