Austin did a measurement for the speed of light in an experiment. He found that the speed of light is 4.0 x 1018 m/s in air. When Nancy Drew saw his result, she immediately informed him that he made a mistake. How did Nancy know? O Light cannot have a speed. O His result would be correct if the experiment was done under water. O His result would be correct, if the light medium was in vacuum, but not in air. O None of the choices is correct. O Speed of light cannot be greater than 3 x 108 m/s.

• (a) How rapidly does the distance between you and your mirrorimage decrease if you walk directly toward a mirror with a speed of2.9 m/s?
For an independent study project, you design an experiment to measure the speed of light. You propose to bounce laser light off a mirror that is 54.5 km due east and have it detected by a light sensor that is 115 m due south of the laser. The first problem is to orient the mirror so that the laser light reflects off the mirror and into the light sensor. (a) Determine the angle that the normal to the mirror should make with respect to due west. °(b) Since you can read your protractor only so accurately, the mirror is slightly misaligned and the actual angle between the normal to the mirror and due west exceeds the desired amount by 0.003°. Determine how far south you need to move the light sensor in order to detect the reflected laser light. m
