2) A lab group decides to do an experiment with their |OLab to measure the light intensity of three settings on their phone flashlight. They set the phone above the light sensor and start recording. Starting with the flashlight off, they turn it on to level 1, then Level 2, and finally level 3. This experiment generates the data shown below. Light (4800 Hz) 8 7 _ 6 3 = 5 = 4 5 3 = 2 , 0 1 0 2 4 : 8 10 12 14 e @ Time (s) The group notices that their data shows a big difference between the measured intensity between off, level 1, and level 2, but that there's not really much of a difference between the measured intensity of levels 2 and 3. They conclude that level 3 must not be much more intense than level 2. Their lab instructor suggests that, even though the data seem to show this result, their conclusion may not true. Based on what you see in the graph above and what you've Learned in this activity, try to explain the lab instructor's reasoning. What might this group do to make a better measurement of the difference between Levels 2 and 3 on their phone flashlight
