- This is a part of a review I'm studying, NOT a graded assignment, please do not reject. Thank you!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.Ⓒ Macmillan Learning The speed of a light wave in a certain transparent material is 0.661 times its speed in vacuum, which is 3.00 x 108 m/s.
