Assume the distance to the Moon is precisely 3.84108 m and Earth’s atmosphere (which varies in density with altitude) is equivalent to a layer 30.0 km thick with a constant index of refraction n= l.000293.

Which of the following best explains the reason for taking three measurements at each light intensity instead of a single measurement? Select one or more: a. By taking three measurements at each light intensity, the investigator could identify any result that was not expected and repeat the measurements until the expected result was obtained. b. By taking three measurements at each light intensity, the investigator could eliminate any result that did not support the hypothesis. c. By taking three measurements at each light intensity, the investigator could be more confident in the accuracy of the measurements than if the measurement had been made only once.
